OS X 10.3.8 / PTLE 6.7cs9-occasional screen freeze

[KingFish]

No big deal, however 6.4cs9 did not do this and 6.7cs9 is doing this on 3 different mac's, it may be related to background task, such as autosave, or digidesign database writing... however ... occasionally the screen will "Freeze solid" during playback for a few seconds, or until you close, or move a window you're working with. (Mix, edit. plugin etc..)

Now that I see it every day, and the other 2 engineers at the studio have asked me about it, across 3 different mac's I figure it's common enough to scribble this post to digi.

The audio does not stop playback, nothing crashes, the screen just locks up for a second or two.

This seems to be happening on Mac OS X / 6.7 LE only.... I am NOT getting this on TDM 6.7 / XP - PC
