With the 1/27 version, LabView still sometimes show a partial frame, even with the serial port delay set to 4. I see little difference between a delay of 1 and 4. One difference now is that when LabView shows a partial frame, the red LED keeps blinking for the usual duration, the blue progress bar disappears, and no error is posted. LabView is still in run mode, and I can select Grab Frame again - which may or not show a full frame.
My earlier post was misleading. The serial port buffers are set to 14 and 15. I had thought you meant a software buffer. And many (~50?) WinXP processes are running in the background; most, I have no idea what they do. Maybe one of these sometimes prevents LabView from fetching the data?
I can operate LabView CMUcam2 GUI reliably on my desktop; Grab Frame works 20 times out of 20. But that is faster, with fewer background processes.
