@DiapDealer,
And as BeckyEbook pointed out the src/Dialogs/ClipboardHistorySelector was made non-modal and so it has that extra min window hint recently added too. When you revert those other two, you may want to revert it as well, just to check.

Those were the only 3 that were recently added. The About box was never touched. The fact that it added a minimze button too under Windows is very strange. So you might want to comment out my attempt to forcibly remove that hint if present first just to check as it should not have been impacted by the changes made for the other 3 were. The MainWindow should automatically gets the min and max enabled.

Is that min button appearing someplace besides the About Box that it was not meant too?
