ProTools 9 Intermittent Screen Freezing
I'm hoping someone can help me out here. I've seen others online have this same problem, but I've never seen it resolved. I've spent hours searching the DUC, here on Gearslutz, and the web and can't get an answer.
Any time my ProTools 9 session gets up around 67%+ of system usage, the screen starts freezing randomly. The audio will still play, but the screen is frozen. I have to repeatedly hit command+option+esc for about 20-30 seconds before it snaps ProTools back into reality. It is incredibly intermittent…sometimes happening every minute or two, sometimes once every 10 minutes. And unbelievably frustrating and disrupting to workflow.
I've done all the obvious stuff…killing preferences, repairing disks, changing hard drives, save session copy as, etc, etc.
Once I saw someone mentioning doing some stuff in Terminal about changing something with the graphics from "yes" to "no", but I'm not smart enough to figure that stuff out on my own.
Any help would be greatly appreciated!
Running ProTools 9.0.1 (though this happened, along with other bugs on subsequent PT9 updates. This version is the least buggy for me, but this one still persists)
