Mail is not launching or quitting and then stopping me from restarting or shutting down.
Mail opens from my dock when I start up and closes after work but will not quit from the dock and also stops me from restarting or shutting down, this message comes up
I can action a Force Quit but then Mail will only open until I restart my Pro.
Running OS X v 10.7.5
Mail 5.3
No software updates availble of updated within the past week.
Any idea's?
MacBook Pro (15-inch Late 2011), Mac OS X (10.7.5)
