Screen resolution keeps changing

I use my mac mini with a usb kvm switch. When switching back to the mac I sometimes find the screen resolution has changed to 800x600. I know the kvm isn't providing mouse / keyboard emulation so I assume the same for the monitor. Will OSX sense this and change the resolution?

Is there a way to lock the resolution to stop it changing? There isn't a padlock in the settings...
Thanks
 
If i plug my mini vga adaptor into my iBook the res changes to 8x6 if nothing is plugged in.

So maybe it feels like no display is plugged in and is resetting or something..
 
If it can't detect the type of external display it resorts to its failsafe setting that should run on almost anything which is 800x600. KVM's will throw the settings out completely, I have never managed to get one working sucessfully on a Mac.
