Projector Changing Resolution

I have a PowerPoint presentation on my laptop, which is hooked up to a projector. The default resolution on the projector is 1024X768 and the laptop resolution is set the same. When I go to full screen on the presentation, the display settings change on the projector to 640X480. And as soon as I exit, the resolution returns to default.

Laptop is Dell Precision M90 and Projector is an InFocus IN5102. It's connected via VGA. I have the latest drivers on the laptop's video card (nVidia). I checked the settings on the laptop video adapter as well as the projectors settings and nothing I have yet tried is working.

Any ideas?

Check the settings of the second monitor in display settings.
When you change to the projector with Fn+Crt/LCD keys, it use following sequence:
1 press: both laptop and projector
Press the key combination again: only projector
Press the key combination again: only laptop.

Cycle through it and see if the resolution is fine when only on projector.

I followed your suggestion for cycling through. While doing so I happened to notice that (when only on the laptop), the resolution seemed to change (I caught the XP taskbar before it went away- at a smaller resolution). I then went into the settings of PowerPoint under Slide Show>  Set up show> and (Performance) Slide show resolution> which was set to a manual 640x480. I set it to the auto [Use Current Resolution] and it resolved the issue. Much thanks ThrainSonOfTimor.
