Additional Information:
This issue with the tabs and the highlighting after a minimize and restore only happens if you use the taskbar thumbnail to restore the group.
If you only click the taskbar icon for the group to minimize and restore the group, or if you minimize the group by clicking minimize button on the title bar and then only click the taskbar icon for the group to restore the group, the tabs behave as expected.
This doesn't happen with Groupy1.5, but then it wasn't designed for Windows 11. I'll also add that "Show preview thumbnails of inactive tabs on mouseover" also doesn't work. What I take from this is that something has changed in Groupy2 with how it handles thumbnails.
If you can't reproduce this on a Windows 10 machine, I guess I'll just have to live with it. I don't really use taskbar thumbnails since it's easier to just click on the tabs. I also never had "Show preview thumbnails of inactive tabs on mouseover" turned on with Groupy1.5, so I won't miss that feature. I really only use Groupy for File explorer, Notepad, and Wordpad, and I also never save any groups. I use something else for tabs in Microsoft 365.
Thanks for listening. I appreciate all the hard work the developers have put into this new version of Groupy!
