This is mostly a service release that fixes some bugs, while also improving keyboard / accessibility cues for some dialogs. Get it via the built-in updater, or from the website: http://www.getpaint.net/
Fixed: Pasting an image from Office 2003 applications now works (e.g. Excel 2003 graphs).
Fixed: Some dialogs were not indicating which command button was the default. These buttons now have a highlight to indicate which one will be activated if the user presses Enter or Space.
Fixed: Some minor keyboard navigation issues with task dialogs
Fixed: Performance issue with the File->Acquire submenu taking a long time to appear
Fixed: Window activation issue when the Print wizard was finished / closed
Fixed: Crash when there was 1 image open and the user pressed Ctrl+Q and then Ctrl+W
Fixed: Minor performance issue if the user had 1 modified image open and then canceled the “Save changes?” dialog
Fixed: Misbehaving filetype factory implementations (plugins) will no longer cause a crash
This is mostly a stop-gap release to fix some bugs before work begins in earnest on the next release with some cool new features. Stay tuned!
