Need help with powerpoint on my macbook

[digger]

I am having a problem with running a Powerpoint slideshow from my Macbook. During the slideshow, I want to back up to a previous slide. I am using a remote to run the projector. To advance to the next slide, I click the main button on the remote, to back up to a previous slide, I want to hit the “right-click” button on the remote. Instead of backing up, I get a menu on the slide which says: Help, Next, Previous, Go, Meeting minder, Pointer Options, Screen, and end show. This is the same menu that I get when I double click/right click on my touch pad during a slideshow. Does anyone know how to set the remote or my macbook to make the slideshow back up when I right-click on the touch pad or on the remote?
Essential data is:
Microsoft Powerpoint X for Mac, Service Pack I
Macbook running Mac OS X
Sony Data Projector VPL-CS6

Like I said, use the left arrow on the remote.
