Mum bought a Logitech QuickCam webcam. There really isnt a lot of documentation with this thing.

It was installed over a week ago. When she's chatting the screen goes black and frequently she has to reboot the computer. She's using the most recent version of Yahoo Messenger. Scandisk is coming on telling her she's getting allocation errors. She's getting illegal operations windows.

Her computer has:
128mg ram
400 processor
20gb harddrive
win98se
usb 1.1

She's within the recommended specs. We would appreciate any assistance. Thanks
