Actually, it seems that whichever iCam Source is launched first, that is supplying the video for both accounts regardless of which is "active" and only the first account has audio. Even if the iCam Source #2 is QUIT/OFF/not running/uninstalled, if we're logged into Account 2 on the computer, we see the video from iCam Source #1 that is set up on Account 1. It doesn't matter what audio setting I have on the 2nd iCam Source to launch.
Since both computer accounts are using the same USB camera, this would be great... IF the audio worked for both accounts. But I lose the audio in the 2nd account rendering the program useless for me half the time.
The microphone is a built in mic on the face of iMac display. Do you think a 2nd camera with audio or a 2nd mic or just an external/not built in mic would solve this?
