Never disable the second display

[FreQi]

I have an nVidia GeForce 8600 GT and I'm using v169.21 forceware drivers on Windows XP with two monitors, one is a 17" LCD on a DVI->VGA adapter as the primary monitor, and the secondary is a Panasonic 720p Projector connected via DVI. I've noticed that when I turn off the projector, I hear the windows tone that indicates removal of hardware. When I turn the projector back on, I hear the "connected hardware" tone, but the extended desktop is not shown - it's just a blue / no signal screen and I have to go into the Display Control Panel and re-enable the extended desktop. the resolution is set correctly, I just have to check the box and click OK.

I have Mediaortal set to start in full screen on the secondary display (the projector). So if I have it running when I turn off the projector, things seem fine, but when I turn it back on, MediaPortal jumps to the Primary display, but it's all messed up in the background and I can't click on anything. It's really irritating.

Does anyone know of a way to force windows to keep the secondary display or extended desktop turned on even when it thinks the projector is disconnected/off? I'm willing to get some sort of hardware trickery that might make the video card detect a device there if such a thing exists (dvi switchbox maybe?) but I haven't found anything.

Anyone else found a way around this?
