Thanks for that mate !
Just to clarify though....you are able to use the page up/page down keys at the first instant the PC freezes ?
i.e. the mouse/scroll routine has frozen the PC but using your page up/page down 'work around' you unfreeeze the thing ?
I shall keep your idea in mind the next time it happens. It has also given me the idea of using the wheel on my mouse as a possible 'work-around' too.
Cheers,
