If you are connected to another CU-SeeMe user or a reflector, the Send button
will be enabled when any other participant has their slide window open
and has your video window open. When you press the button, the current slide is
sent and a progress percentage is displayed. The transmission happens in the background.
Images grabbed from the video camera will show up in the slide window
of CU-SeeMe versions prior to 0.87, but screen captures and pasted pictures will
be ignored by previous versions. Windows users will not be sent the slides.
The Send button will be dimmed out in
Remote Mode or when there isn't a slide
to send.
