I'm new with MC and noticed a strange behaviour...
It happens from time to time, that a modal window (like the one to select the right album when ripping a disk) appears BEHIND the main window instead of overlying.
In this situation, MC seems to be "not responsive", because the modal window appears in the back while the main window in the front has the focus... And the main window doesn't accept any actions due to the existence of the modal window in the back.
I discovered this behaviour on my Mac (BigSur) using Mission Control [F4], where all windows are showing next to each other (see picture).
This seems to be a bug where MC is not handling windows and focus in the right way.
Unfortunately I'm not able to reproduce this behaviour... this happens from time to time in combination with other apps I'm using simultaneously like Safari, Finder, Mail etc.
Can somebody confirm this conspicuity?
