[Interest] Debugging a double dealloc

[Tony Rietwyk]

Hi Ben,

There may indeed be an issue with fonts being tied to having at least 
one window present, which causes you grief when you delete the main window.

Have you tried the suggestion from your other thread to just hide the 
main window instead?

Where is the tick font used?  Does your main menu that you want to 
persist without any windows use it?

Have you tried a cut-down app that creates a plain QMainWindow, a plain 
main menu, then destroys the main window to see if persisting the main 
menu is actually doable on Mac?

Regards, Tony
