CamTwist works during web chat when using login on computer that has admin privileges. But it doesn't work at all in another login that does not have administrator privileges. After giving permission for the webcam, there is a prompt for which webcam to choose, and CamTwist does show up there. But nothing displays but empty black square were my CamTwist content should appear.
Is there some sort of permissions that CamTwist needs? I'd like to make CamTwist usable for all accounts on the computer, but without making the other users on the computer administrators too.
