What do you mean exactly by "it totally refused to accept my PPT file"?
Do you mean the PC laptop would not recognize your flash drive?  Or do you mean you loaded the PPT 
file and it would not run in standalone mode? Or do you mean the copy of MS PPT on the PC (if it had 
PPT) would not open your mac PPT file?

The fact that your mouse cause the PPT file to freeze your machine sounds really weird.  Projectors 
are pretty agnostic as long as you can get a video signal to project at all. I assume you have 
properly reduced your image sizes before putting them in the PPT to minimize the computer's efforts 
to push the data out the extra video port?

I assume you have tested this PPT with a different second digital projector to make sure it is not 
your computer that is having the problem with PPT and your mouse?

I assume you ran other programs like Photoshop, with a mouse, without problems?

If you need a projector, they are great to have for presentations, as a backup if nothing else.  You 
should be able to get a good product for $800-950. But the replacement bulbs are where the companies 
make their money, so make sure you buy a good bag with it to protect it.

Check out Amazon for Optima, Proxima, and Infocus projectors.  You want something with 1024 x768 
resolution and at least 1800 lumens, though most are now over 2000 at this price range. These things 
are really small now: 2x8x8 inches, 3 lbs, is not unusual.  Look for one with a DVI and VGA 
connector.  Also pay attention to the Decibel rating and warranty length. This one is probably more 
than you need, but it has lots of nice features:

This site has technical data on projectors:
