[Feature Request] When PE is the only foreground window open, don't lock the mouse

As the title. I noticed that if PE is the last open foreground window (ie the only one remaining on the Taskbar), it will lock the mouse and of course there is no alt-tab option, as there are no other windows.

Have to hit the Windows key to bring up another window of some sort. Anything will do eg explorer window. Under most circumstances at least PT or Steam would be open, so I didn’t notice this at first.

If there’s any way to detect this and prevent mouse lock, it would be nice. I suppose one alternative would be to turn off the PE mirror window completely. Is that possible from the options?

Thanks!
