Working all morning on a mockup stored on the cloud. All day I have been unable to undo - can't CTRL Z and the Edit > Undo is disabled.
I eventually get sick of not being able to make mistakes so I decide to exit and relaunch. Unfortunately I can't. Pressing the close red X doesn't do anything. Going to File > Close doesn't do anything. Alt+F4 does nothing. So I go to task manager and kill the app.
I re-launch and all the work I have done is gone - and I still wasn't able to undo or close the application.
The application has been performing very poorly in recent weeks. It crashes on me at least once a day. 2 or 3 times a day something strange happens - like I can't edit text or move things until I close and re-open the application.
