Unimplemented trap

Mon, 1 Sep 1997 11:46:25 -0400 (EDT)

I'm on a Mac, Performa 636CD.
After about 12 minutes of uninteruppted CuSeeMe use, I keep getting an error
message telling me about an "unimplemented trap"... everything freezes and I
have to restart.
What am I doing wrong please?
Any help would be greatly appreciated
