Here's what I got:

Mac G3 (Blue & White) with a ZIF G4/500 upgrade. 384 RAM, 120 gig main
drive, 80 gig recording drive.
Running Panther (10.3.9). Delta 44 PCI card

I've had this Delta 44 card for about 5 years and it's always been
fine, running in OS 9, OS X Jaguar, and now in Panther since April. I
recently got Logic Express 7 and was testing it to make sure it would
run on my older machine. I brought in 10 tracks of audio from an old
song and it played fine. But yesterday, when I played it and hit stop,
Logic would repeat a clip over and over (stutter).

So I fiddled with all the audio prefs which didn't solve the problem.
So I thought, maybe I should download the latest M-Audio driver. This
is where the REAL trouble started!

I installed the latest Delta Driver from M-Audio's site. After it
installed and did a restart, the Mac had a kernal panic. It had the
grayed out desktop with the message in the center to press restart
etc... I restarted with Shift Key down to boot in safe mode and ran the
unistaller. After taking the M-Audio driver out, it restarted fine.
Repeated with earlier Delta driver from their site and got the SAME
thing.

Any thoughts on what could be causing this? Now I don't know what
earlier driver I should install or if there's something else
conflicting with it. Should I run the latest System update from Apple
and then try again?

Thanks.
