Hi Dave,

I've been researching this in Google and Microsoft's Knowledge Base, and can find little reference to it, except one article in Microsoft, here at this link

Unless anyone else knows how to help, have a look at that.

Questions;

When did this start to happen? Was if at any particular point? ie did you install something, or re-instal XP, or something else?

Have you tried to access any of the Control Panel Applets whilst in Safe Mode, or access Display Properties thru right clicking the desktop in Safe Mode?
