Screen Resolution Keeps Resetting

[MrTBC]

Hi.
I have a user on XP SP2 whose screen resolution keeps resetting at random intervals. By default it is 1024x768 but we have manually set this to 800x600 for her. This setting will stay for a while, and then one day she will log on and it will revert back to 1024x768 again.
Can someone point me in the right direction here please?
Where is this setting stored?

Thanks very much guys.

It is a registry setting, but remember that the setting is global for all users unless some additional tricks are employed.
