Although I have not received any response from the Cu-SeeMe developers or
from users who knew what the problem could be, I would like to thank the
handful of other MacIIci users who e-mailed me directly saying they have
the identical problem. I find some consolation in the fact I'm not the
only frustrated Cu-SeeMe user.

I tend to believe the lock-up problem is with the way Cu-SeeMe handles
serial port audio. The Connectix supplied software and inits works well
enough through the serial port when recording QuickCam audio for QuickTime
movies and sounds. But with Cu-SeeMe the MacIIci locks-up even with
Cu-SeeMe audio sending switched off.

For those who are trying to use Cu-SeeMe and the QuickCam, I recently found
that Cu-SeeMe will work most of the time on the MacIIci if the ~QuickCamMic
init is disabled or removed. Of course with it removed, you can't record
audio for do-it-yourself QuickTime movies. But, you can listen to other
Cu-SeeMe user's audio and get a moving picture out on the net.

Regards,

Doug
