#979 Froze application MacOs with separate window 3D view

[Stephane QUILICHINI]

Design something not complex (just put 2 or 3 objects without wall).
Show 3D view in a separate window and maximize it.
Go into the menu and try to quit.
Window close but application is still active and cannot be recover --> task manager and force to quit is the only solution.
Sweet Home 3D 6.4.3 on MacOS BigSur Beta 6 or 7.

[Emmanuel Puybaret]

Probably fixed in BigSur final release.
