And an adjunct to that.
If a notice or alert window pops up
or
if any other information window has yet to be answered (yes, cancel, select some action etc.)
Then
If MC is sent to the background
you HAVE to click on that notice or alert or info window before the MC main window will respond.
This also includes trying to bring the main window to the foreground, to be able to to get to the notice or alert window.
IOW you HAVE to clear any and all notice or alert or info windows 1st, before the main window will respond to control inputs (keyboard or mouse).
Not a big deal except when trying to click on a mostly buried main window to bring it to the foreground and it won't respond. This forces you to 'clear' the area and find the notice or alert window to clear it first so that the main window can be controlled again.
