I've had my first kernel panick today. I thought that they were a myth, a bit like a unicorn or a cyclopse. Ever since I installed OSX 10.3.9 (via software update from 10.3.8) I've had nothing but problems. Initially everything was fine, my banking websites did improve in speed. However, if I load multiple tabs in Safari, my machine will freeze until all tabs are loaded. Safari will hang occasionally. The powerbook has locked up twice and Mail will hang with any graphics intensive web pages. I've had the iTunes Music Store crash too! It seems that Safari 1.3 and its SDK (used in Mail and iTMS) have problems, as it is always when bits of Safari are in use. It seems to get worse the longer the Powerbook is on (I tend to leave it on sleep when not in use). A reboot makes everything OK again until the errors start. However, all is not lost. Tiger is on pre-order and after a backup of important files, I will do a wipe and re-install. Has anyone else experienced similar issues?
