[AG-TECH] Accessgrid 3.1 can't unmute local video displays

Hello AG wizards,
We've been trying to set up our AccessGrid 3.1 client here at Indiana
University. We are using Python 2.4, Python 2.4 win32 extensions,
We have three cameras connected which, when tested outside of
AccessGrid, function appropriately. Our sysadmin has recently updated
the drivers for these video capture card and we get a clear picture from
each one when testing with videum configuration application. The video
capture card is a Videum 4400VO.
The problem we're seeing: We can connect to venues and receive
video and audio from other sources, and we can transmit audio. But when
we try to uncheck the 'mute' checkbox next to our local video displays,
the checkbox does not respond.
We have three cameras configured as video producers with port as
external-in, encoding as h261, and standard as NTSC. Only standard
gives an alternate option, PAL, which also has not worked.
We've tried both the newest driver for our video capture card, as
well as rolling back to the driver on the CD that came with the hardware.
On some level this seems like it might be a Tcl/TK problem. Besides
the 'mute' checkbox being unclickable, we've often observed that other
windows with "TclTK" in their title (autoplace, for example) have no
elements that respond to mouse input. When this behavior occurs, even
the minimize and maximize buttons on those windows do not respond.
Any help you can offer would be greatly appreciated. :) We are
quickly running out of ideas on how to get this to work. I'm more than
happy to provide additional information as needed.
