I'm posting a message originally sent to the Powerlist (discussion of Mac powerbooks). There were several response, but that directly answered my questions. Since the program is question is Emailer (2.03), I thought this group might help.
--------------------------------------------------------------------------- - 'listers: Based on postings here and on the Mac-L list, the collective consensus for the cause of kernel panics is hardware, e.g. bad RAM, funky USB hubs, faulty firewire chipsets, etc. But last night my 15-in Albook (1.25ghz/80GB/Superdrive/Extreme/Bluetooth) panicked while reading email. System is OS X 10.3.3 with no 3rd party extensions (or system preferences; is that the term for the X equivalent of extensions?) The laptop was, well, in my lap, on my couch, connected only to my ABS extreme while reading email (via Claris Emailer). Obviously Classic was running as was Safari and iChat. Bluetooth was off (I don't have any bluetooth gadgets yet). I had just clicked on the "priority" field in emailer to sort mail when the panic occurred. X is stunningly more stable than OS 9 for me, but it has panicked several times since I bought the powerbook (late Jan. 04); this is the just the first one where hardware wasn't involved. And I'm still trying to figure out why Classic quits without warning whenever I use Internet config. to disconnect from my ABS modem at work. Cheers. bevon ___________________________________________________________________________ To unsubscribe send a mail message with a SUBJECT line of "unsubscribe" to <[EMAIL PROTECTED]> or <[EMAIL PROTECTED]>
