kernal panic crash, BAD

[winwoodb]

I have a g4 yikes/panther/500mb/old desktop. When I have any app left open doing nothing or performing a job, like burning a dvd or cd for a long period of time without any mouse clicks, the computer crashes. I get the greyed out panther 10.3.2 screen with the circle power button sign saying I have to restart. Then I lose, wasted, my 1/2 burned dvd only to start over, same thing over again.Seems mostly related to toast 6.0.1 All apps are updated to panther, including mouse. Not sure about something called application enhancer, APE, in sys prefs? Otherwise, when I am working normally, surfing, emails, typing etc. it's all fine. Any Ideas??
