I got a new presentation remote for powerpoint at our church. Everything works except the next and previous buttons. I figured out that the remote sends a page up and page down command with those buttons, but powerpoint uses right and left arrows. Is there something I can change in powerpoint to use the page up/down keys? I tried all the settings on the remote. I'm using powerpoint 2003 sp2 and windows xp pro sp2. The remote works perfectly on another computer with a newer version of powerpoint.
