The Mail app kind of froze on me.
Happened after I had it sync.
The UI of the Mail app still works but the Charms bar is gone and can't be called up.
Alt+Tab works but no matter what the Mail app is always on top and over anything.
Alt+F4, swipe down doesn't work.
In the end I had to Ctrl+Alt+Del and sign out and sign in.
Anyone had this problem before?
