I just had my first Jaguar Kernel Panic. I think it is related to QuickTime 6.1. I had double clicked a movie my brother sent me. The QuickTime Player launched, but the frame didn’t fully draw.
I could not force quit the player and as soon as I lauched another application that used QuickTime, I received the kernel panic screen (telling me I needed to shut off my computer)
I will keep an eye on it and see if I can track down the true source. I hope it does not happen again 🙂
