At work, I use someone's TiBook with 10.2 installed. We were trying to figure out how to use an LCD projector so that the projector can show a slide show from powerpoint while on the TiBook one can look at their notes. We tried a few times and actually ran into the problem where we could control the arrow on the LCD projector but then couldn't get it back to the TiBook (and needed to restart, force quitting the Finder didn't work).
Any ideas?
