Epson Projector causing presentations to zoom to 400% / max font size

I have a client using a Dell Latitude D820 laptop connecting to an Epson Powerlite 76C overhead projector in a conference room setting.  

When running presentations either through Word, Powerpoint, Media Player, Internet Explorer 7.0, etc, etc when working just off the laptop everything works fine.  The moment you plug in the projector and do a "Fn+F8" to duplicate the screen onto the projector for presentations everything goes strange.  While in Powerpoint all slides zoom to 400%, if you start the presentation and click the mouse to advance the slide it immediately goes back to the first slide.  There is also a error sound of a stuck key while the presentation is running.  When in Word or Outlook all text in emails and documents changes to max font size (possibly just zooming cannot confirm).  When I would go into Internet Explorer to check for updates and driver upgrades the screen would reduce in size to 10% as if I were pressing and holding "Ctrl -" (minus).  

After spending about 3 hrs trying to get this working (During a board meeting no less), updating drivers, changing resolutions, verifying no stuck keys, disabling and reenabling devices (ie touchpad/mouse "eraser nub"/mouse from a desktop/keyboard, I ended up plugging the projector back into the 15 pin vga connection, enabling the adapter as an extended desktop.  This allowed me to to utilize the "Use Presenter View" in Powerpoint and place the Powerpoint presentation on the 2nd monitor (the projector in question) and temporarily allow my client to go on about his presentations this week.  This however is not an "acceptable longterm fix" as he wants to be able to duplicate his screen on the projector so he show videos, etc.

I am completely baffled by this issue to be honest.  I've asked all the other Networking guys on my team at my office and not a one of them has seen or heard of an issue remotely like this.  The only thoughts anyone has had is that it might be related in some way to handicap accessibility features, but this would effect the laptop when the projector is unplugged as well I would think... it also wouldn't explain the stuck key error sounds either.  Another thought was that it was related to display settings for the projector however it will not show in Device Manager or in display settings to adjust anything, but again this wouldn't explain the before mentioned issues even if this were the case.  The laptop is running Windows XP SP3 fully patched, Office 2007 again full patched, Internet Explorer 7.0, on a Dell Latitude D820, connecting to a Epson Powerlite 76C Projector.

Any help would be GREATLY appreciated.

Any chance you're also using a wireless keyboard?  If so, there's a zoom option that also uses the Fn+F8.  You'll need to disable this option or not use the wireless keyboard.
If that doesn't do it, try uninstalling IntelliPoint mouse drivers

Set both the PC and Projector's Display resolution to 1024 X 768

I tried uninstalling the Intellipoint drivers however it forced a reboot after uninstalling and once it came back up auto-reinstalled the drivers.  Also it would not allow me to merely disable them either.  No wireless keyboard int he mix only the laptop's builtin keyboard.

I'll try setting the laptop to 1024x768 next time I'm at the client's site although I'm pretty sure I tried that already.  Being that there was a conference in progress at the time I was unable to do much tinkering with the projector itself to see what resolution it was set for.  This is for a remote client so I'll have to wait until I can schedule a time to come out there again but will keep you posted.  If anyone else has any thoughts int eh meantime please go ahead by all means but the link provided reguardign changing resolutions sounds pretty close to the issue at hand.

My apologies for forgetting about this as I've been a bit busy as of late.  One of my team went out to work on another item at the client's and while there looked into the projector problem.  Long story short there were multiple dead Intellipoint drivers in the registry that were causing the problem.  Once those were cleaned out all was well.
