Thanks Cammy, I have followed that
as this is an intermittent fault I wont know for sure if what you suggested works for a few days but fingers crossed,
Dave, they all scream at me for having KaZaA but I switched to the Lite version and I quite like that program, if the problem persists though I may well have to think of deleting it (before anyone says, I didnt like WinMx
)
Thanks again guys for the advice
