Just an update, we completely re-installed 10.4 on his system last 
night, and all appears well! At present he is NOT using compiz, or the 
3d screensavers, going to introduce them slowly of the next couple of 
days to try and pin down what is causing the issue.

For info so far we can rule out the Nvidia current driver as this is 
installed and active, and the problem does not seem to be there.

Thanks for all your suggestions and i will keep this list up to date if 
the problem resurfaces.
