There are a lot of kernel panics going on around the forums. I was getting them on an iMac DV SE , but I also had a display problem that forced me to buy a new eMac (1 gig Apple ram, 80 gig H/D) The kernel panics returned and I started troubleshooting. Did all the maintenance stuff including DiskWarrior, and only used the basic apps ( Safari, iCal, AddyBook, Watson and System Prefs). I suspected Mail because that was the only common denominator to that point. When I fired up Mail I soon got a panic while composing a message, after I had sent and received some items. Should I reinstall Mail using Pacifist? Will I lose all my mailboxes and prefs?
