powerpoint & the OS screensaver

[sam]

I'm pretty sure there was a way of making sure the screen saver doesn't kick
in when you're running a ppt.. question is...
1) where is the CIW is that?
2) where can i also make the modification once powerpoint is already
installed?

thanks
ps..not clear on where this question should go..so i'm also posting it in
the powerpoint section
