I'm back, thanks for helping Stief.

Acq .9.1 would crash. I sent the logs to Dave, and he said it was a random bug he was trying to track down. I didn't bother with .9.2 as I don't think he addressed it in that version. I figured I would wait until he gets back and give the next one a try.
I tried both as an ultrapeer and with it disabled. My network went up to 32 peers and 25 leaves before crashing. With the ultrapeer disabled, I got to my normal
"5 active" and shortly thereafter it crashed as well.

re Kandace's problem: I think I've used Classic about 3 times in 2 years, and I only boot into OS 9 to run DiskWarrior and PlusOptimizer on OS 10. So when her problem expanded into that netherland, it really taxed my memory bank. I had to try and visualize her scenario from the rear view mirror, so to speak. I had wanted to get to the 'get info' windoid to look at that 'open with', but we never got that far.
This is one of those situations where I'd love to have a remote desktop application to see what her setup looks like.
