Strange behavior with PT11

[Ty Ford]

I've recently upgraded to PT 11 from 10.

I've had three occasions when a session jams and all I get are the back and forth play/stop transport buttons.

I've had one occasion where, after moving several chunks of audio at one time, I couldn't get the system to play from where I placed the cursor. it wanted to go back X seconds and play from there. To get out of that I restarted, but still had the same problem. I ended up closing the session and starting one of the auto backup versions. That worked, but made me a bit nervous.

I've also had problems just quitting PT. I once saved a copy to protect myself.

Any solutions to these issues?

Thanks,

Ty Ford
