I was lurde into this update, only to find myself with a hardly usable product.
Doubtfull is: any testing done before release ??
The Main window does not show anymore the:
- windowed mode
- fullscreen mode
- minimize to taskbar
- exit complete and terminate
option icons _-x
thus turning thunderbird into an almost unusable dumb brick.
kindly consider a repair fix on this soon.
best regards, Gunter
