Random and out of control mutes in PT 11.1.2?

[algerij]

I updated my MacBook Pro to OS X 10.9.1 because I thought it was safe to do. I kept running PT 11 however.

I started a new PT session and all of a sudden I have random mutes on particular channel and I seem to have no control over any mute automation when I'm in group mode.

I updated to PT11.1.2 and the problem is still there on any session that I go to.

I also updated the Mbox 3 Pro driver. Nothing else in my setup has changed, running proper external drive, etc.

Anyone had a similar problem??

Thanks Joe
