Do you mean it crashes? If so, what does the detailed crash report say?
If you mean it silently exits - then when does it do that?
And if you have any third party plugins, have you tried disabling them?
It does not crash and it does not exit. It just stops working. I cannot exit, I cannot save, I cannot make any changes. It just stops. This seemingly started after I upgraded to Mavricks.
How do you disable plug-ins?
Thank you for your help.
I end up having to do a Force Quit and then reopen to continue working.
