Default Re: Kernel Panic with Mbox2 USB -- partially isolated problem

I always do what you suggest, but still experience a crash of the OS after using Pro Tools for at least 20 minutes or so.

BUT -- I've isolated the problem, to a certain extent: the problem occurs when quiting Safari or QuickTime. Since I always have at least Safari running just before shutting down, I used to think that the problem was in shutting down. However, if, after quitting Pro Tools (after at least 20 minutes of usage), and after then going into System Preferences -> Sound and making sure that "Line Out", rather than Mbox 2 is selected -- if at that point, I then quit Safari (if it was running too) or quit QuickTime (if it was running too), then the OS crashes, every time.

Here are the specs of my system and my version of Pro Tools:

Mac Pro, 2 x Intel processors, 6 Gb Ram, running OS 10.4.11

Pro Tools, version 7.4cs7, but with update cs8 (the latest) applied.
