PT 7.3.1 - Still Features Random Graphic Freezes

[tclash]

Conclusion: This is a G5 specific problem

Well unfortunately it's not. The freeze happens on my Mac Pro as well. Fortunately it doesn't happen very much. I haven't been able to discern any pattern to when; I can make it through a whole mix on some sessions without a single freeze, but it starts to happen on others. I tend to use more or less the same variety of plugs, so I really don't know what would cause it to happen on one session but not another. Luckily I'm not using MIDI/VI's that often. I have had it happen in the past on sessions with MIDI and the whole note train wreck thing is kind of a nightmare if you don't get your monitors turned down in time.
