What's new in this version:

jv16 PowerTools 5.0.0.527
Bug Fixes:
-The previous version fixed the problem about Firefox bookmarks being modified or removed during System Cleaner. The original bug was rare, only occurring in some systems. The last version fixed it for many users but not perfectly. This build now fixes it for good
-The program may fail to start on some systems. If this happens, you will only see the initial splash screen and nothing else ever shows up
-The Initial Setup can take a very long time to run on some systems
-Tools menu > Maintenance > Flush Cache does not trigger the Initial Setup to run again, even if it says it would
-If you don’t have a browser installed, for example Firefox, the System Cleaner will still search for its cookies and history data. This makes the scan a few seconds slower than what it should be
-System Cleaner can incorrectly say no items found even if some were found
-On small screens the splash screen’s bottom texts can overlap the version number text
-System Cleaner can ask for permission to close web browsers even if you have selected not to run any browser related cleaning modules
-System Cleaner can search for temporary files even if the temporary file scan module has been disabled from Settings
-The Ignore List may not work in cases of you want to ignore certain types of registry data, and the System Cleaner will therefore continue to list this data
-Starting the System Cleaner can show confirmation text in English, even if you are using the program in another language
-The program can display Stringlist Out Of Bounds error when starting. This is a very rare issue, happening only in some systems
-Ignoring software with the Software Uninstaller via the Right Click menu does not remove it from the list, it is only not shown the next time even though System Cleaner removes the item from list immediately after item is ignored
-Internet Optimizer can get stuck in the Starting … screen

Feature Improvements:
- Improved the detection and the listing of browser cache data
- System Cleaner’s information message boxes are now shown only if System Cleaner is open and active
- Made the user interface for the System Cleaner settings clearer
- Installing a new version of PowerTools over the old one causes in some cases of important (but not critical) cache files never to be created, as the Initial Setup has already ran when the old version was installed. Now, the program will detect if such cache files are missing and perform an Initial Setup again if needed
- Increased the waiting thresholds of information messages in the application to avoid too many tips or other non essential message boxes to be displayed in too rapid progression
- All the three main tool text captions are now visible. Before, only the default tool or the currently selected tool caption text was visible, which some users found difficult to use
- The program will now attempt to detect a running setup of jv16 PowerTools and automatically close itself. This way you are not prompted with an error message of a file in use if you try to update while the program is still running
- My Account’s Apply button is now only visible if needed
- Aborting a scan can cause the user interface to get not responsive. Therefore, the Aborting scans feature is currently not available until we improve and fix it


jv16 PowerTools 5.0.0.513
Bug Fixes:
- Choosing to clean the cookie or history data of only some browsers in the Settings window can cause the System Cleaner not to clean any browser cookie or history data
- The “Congratulations! No errors or unneeded data found from your computer” message may get stuck in a loop and displayed over and over again after the System Cleaner
- The top one pixel of the message box window’s buttons many not be visible if the system is using higher than 100% font size setting in Windows
- Fixed a misspelled word “erros” from the English user interface (should be “errors”)
- The check for multiple program instances is not always working, allowing user to run multiple instances of the program at the same time
- Internet Optimizer can edit the DNS settings set by installed VPN or internet security software suite. This has now been addressed by detecting these settings and informing user that the Internet Optimizer cannot be run in this case
- Running the Software Uninstaller can display an error message relating to converting date. This is a very rare issue, happening in under one system in one hundred
- The scan progress screen can display lines starting with an empty space character. This is a cosmetic issue but fixed now nevertheless
- The program can display gray color panels behind texts if user is using Windows with the classic theme or high contrast theme enabled
- Uninstallation of software with the Software Uninstaller can display the warning message of uninstalled software being similar to another software multiple times
- The System Cleaner can list firewall policy registry entries which are recreated by Windows
- Adding a drive letter to the Ignore List will not prevent software from that hard drive being listed in the Software Uninstaller
- Closing the program too soon after running the Initial Setup can cause the Initial Setup to be run again on the next time the program is started
- System Cleaner’s check boxes are incorrectly aligned if user’s system is using large fonts in Windows settings
- The program can fail to detect installed browsers in some systems and this causes the browser cleaning options of these browsers not to be visible in the Settings > System Cleaner and also not run during System Cleaner
- Some texts from the user interface cannot be translated, i.e. they do not exist in the English.txt file
- The color of the background panels in System Cleaner’s report screen can be incorrect
- The program does not correctly Windows language if it was changed by the user. For example, if you installed English Windows but then downloaded a Windows language pack to change its language to Polish, jv16 PowerTools will not automatically detect and load the Polish translation.
- The program does not close itself if it is still running when user starts the uninstallation of jv16 PowerTools
- Clicking to Abort a scan may cause it to get stuck to a screen with text “Starting …”
- Cleaning browser history data could cause browser bookmarks also be removed or altered in some rare cases

Feature Improvements:
- System Cleaner now lists all the browser history and cookie data per domain, allowing you to choose what data to exactly clear
- The trial reminder or license information text at the bottom right corner of the main window is no longer clickable during the scan progress screen to avoid accidental clicks
- Improved the smoothness of scrolling the System Cleaner and Software Uninstaller result lists
- Improved the scan progress screen’s user interface smoothness. It should now show and update with far less element sizes being changed for no reason
- The Settings window’s Domain Whitelist and Global Ignore List features now automatically remove unneeded rows of data. For example, if you would enter “jv16 PowerTools” and “jv16” to the Global Ignore List, the row “jv16 PowerTools” would be automatically removed as it is already included in the row “jv16”
- Some users have been confused by the Invalid Metadata errors found by the System Cleaner, thinking that such error means that the file mentioned would be deleted by the System Cleaner. This is not the case. For example, if the System Cleaner reports that Explorer.exe has invalid metadata, it does not mean the file would be deleted. Instead, the System Cleaner would only fix its invalid metadata from the file system record
- Improved VPN and firewall and internet security software detection
- Internet Optimizer now refuses to start if the system is using local network based DNS to prevent any compatibility issues, for example with locally run network solution, VPNs, internet security software or locally run servers
- If you enter full URLs to the Domain Whitelist in the Settings window, the program will now know how to process them and only add the domain names
- Added an option to delete unused translations and clear jv16 PowerTools cache files (Tools > Maintenance menu)
- Added an information text to My Account’s user interface to inform the user that an internet connection is required. This is not shown if a connection has already been detected
- Attempting to activate a license in My Account without newsletter subscription setting will now automatically scroll the setting into view
- System Cleaner will now show more information messages relating to the found items. These were designed to address some of the common misconceptions of the results
