unable to change display resolution after installing Logitech QuickCam

[jgoodman00]

We installed a couple of logitech quickcams yesterday, & since then you can no longer change the display resolution of either computer. I have uninstalled the quickcam software, unplugged it, & removed all registry entries. This did nothing to resolve the problem, so I went back into the registry & have found that I can change the resolution within the registry (i.e. by typing in the resolution I require, & then restarting the computer). To make things slightly stranger, I have found that sometimes after doing this, the display resolution can be changed in the normal way, but only for a limited time. After a short time (approx a few minutes) the display can no longer be changed.

Has anyone ever encountered anything like this before, & if so did you find a solution??? James Goodman
