I've been running PT 7.4 for about 4 months now on the same computer, and it seems like it's running shittier and shittier, even though my sessions have been much more compact and organized each time. Now it's so bad that even after I printed my Kick/Snare tracks so that I could deactivate the drumagog inserts, submixed a lot of other tracks, and consolidated all of my edits, I can't even make it through a bounce to disk without my computer freezing and forcing me to do a hard shutdown. Is there some kind of maintenance within Pro Tools that I should be doing?
