OS: Windows Vista 32 Webcam: Logitech QuickCam Communicate MP Logitech Software Version: 11.80
Thiswebcam worked fine when it was first installed. Within the first coupleweeks, I began having the problem of seeing a black screen instead of avideo image, with both the logitech software and Yahoo Messenger. A fewtimes, this problem was fixed, by restarting computer, and once byending all related processes in Task Manager, then restarting Logitechsoftware.
Currently, I am only seeing the black screen, andcannot get a video image. I did uninstall all Logitech software,restart the computer, and reinstall Logitech software. The problempersists. I have not received any error messages at any time relatingto this problem. The camera appears to work fine; however, it only shows black.

- Thank you for this very detailed response. I tried the steps you suggested, but they did not help figure out my problem. The amcap application crashed every time I clicked "video capture pin." I checked my DirectX version, and it is version 10.
The strange and partially frustrating thing is that now my webcam appears to be working fine. I guess it is an intermittent problem. I called Logitech support, who told me they can't diagnose a problem while the camera is working. They suggested I call back when it is not working, to see if there might be a conflict with other software that is running at the time.
Thanks again, and good luck to others with this problem.
RGB, I420, or IYUV formats. (Each is fine; we recommend RGB 24.)
