This is an issue I notice happens sometimes while using Spine. After exiting, my mouse and keyboard either doesn't work or the Windows commands get mixed up. I really don't know how to describe what happens to my mouse and keyboard commands. For example, I can click on the tabs in Google Chrome, but clicking my bookmarks act as right-clicking.
This isn't version specific, as I've been updating Spine while encountering this problem. Usually, however, putting my computer to Sleep fixes the issue, but I want to find a solution to prevent this issue.
