Am I not "focused" on the show screen?
Well it was worth a try

Powerpoint is a strange beast at te best of times. We used to have a problem with "Screen Burn" on CRT projectors at work and ensured that all PCs had screen savers enabled. Unfortunately it still didnt save the projectors because presenters would leave corporate powerpoint presentations on the screen usually of the first or last slide which was always the company logo.

Powerpoint disables all screensavers so the projectors still got burnt

Can you get your PIC to fake either a PS2 or USB keyboard instead ?

We used to have a Kodak slide projector IR remote control that was interfaced to the cursor keys on a keyboard for controlling Powerpoint because it had better range than cordless mice and was 100% reliable.
