Webcams

Are there any compatibility issues between webcams and Vista?

Yes. I have seen quite a few issues between webcams and Vista and a lot of times it comes down to the drivers for the webcams themselves.

New problem

My client phoned me yesterday with another problem:

The strange thing is that yesterday it refused to boot up for him, Vista said it couldn't detect a disk, but for me today, it booted fine!
He also got a strange message yesterday, which he didn't tell me about til today, "Security oprions failure"
No clues or errors in the Event Log
Ran a chkdsk - no errors found.
AVG, SpyBot - fine
For some unknown reason, Firefox couldn't connect to the Net, but IE would; I discovered ZA had been uninstalled, but Ron said it was on there before he brought it to me! I installed the latest version, and then put a green tick in the Allow boxes for FF, which solved that - don't know why it disappeared in the first place!
I found out that the error message 'The instruction at 0x768e03fd referenced memory at 0x768e03fd. The required data was not placed in the memory because of an I/O error status of 0x000000e' isn't related to memory!, as 000000 is an unknown address, and that it pionted to network connection problems.
I checked that the network driver was up-to-date, which it was, and that's how far I've got!
