Guys, My wife teaches 2nd grade and has a projector in her room. She wanted to be able to show PowerPoints and other media so I got a VGA adapter and helped her set up her 13" MacBook Pro. It works great. HOWEVER, as soon as we plug the projector in and the MBP screen resolution adjusts (to 1024x768 I believe), the touchpad quits working. If you touch it the mouse jumps around erratically. It is unusable. As soon as I unplug the projector it works fine again. Also, plugging in a USB mouse works fine as well. It is just the touchpad that does not work. I've googled around and come up with nothing. Has anyone else noticed or heard of this?
