Note that when I say "continually", I mean that we consistently get the problem on an inconsistent basis. Sometimes we get it immediately at the start of the work session and it lasts through several restarts of LabView and RC/Camera power cyclings. Other times, things work for a little while (we can grab 2-3 frames), but then we get the OP's problem of LabView not responding to input, not getting the frame that was asked for, and the frame grab progress bar continually filling up and starting over. This persists until we restart the LabView CMUCam GUI application. After restarting, it might or might not occur again immediately. It is consistently inconsistent as to when it works.

If it is really thought to be a power supply issue, then I will try to make an effort to rig up a non-battery supply and run the camera off that. Maybe the OP or someone else having the same problem can do the same (just use any standard DC power supply that fits the specs outlined in the CMU Cam docs).

Hope this helps to diagnose the problem.
Please try the test release version from 2006.01.25 here and let me know what your results are. Hopefully there will be some different behavior that will help narrow down the problem.

Thanks!
-Joe
