This update fixes a few longstanding issues with copy/paste, tool shortcut keys, and tooltips in the Tools window. I’ve also changed the capitalization of “paint.net” to be “Paint.NET.”

Change Log

Changes since 5.1 beta (build 9066):

• Fixed: Copy/Paste has been hardened against short-term intermittent errors and should no longer show spurious error dialogs (e.g. ERROR_ACCESS_DENIED) except in legitimate cases.
• Fixed: Certain shortcut keys, especially for switching tools, will no longer stop functioning if a floating window (e.g. Tools) is hidden and then shown by clicking on the button at the top right of the main window.
• Fixed: Tooltips in the Tools window will no longer stop functioning if a floating window (e.g. Tools) is hidden and then shown by clicking on the button at the top right of the main window.
• Removed the “Scrolling past the edge of the image (overscroll)” checkbox from Settings. This was enabled by default, and now it is always enabled.
• Fixed: The installer was occasionally showing an error about an InvalidGraphConfigurationException on some systems
• Added a KnownColorSpace API for plugins so they can create IColorContexts and IDeviceColorContexts for the Display P3 and ProPhoto RGB color spaces
