OK, I hate to start a new thread as my very first post on a new forum,
but I'm desperate.

I got a new, tiny, laptop for the sole purpose of toting it around to
give presentations.  I installed Office 07 on it, including PowerPoint.
I should note that I installed the bare minimum, with very few of the
extra features.

I usually use a CPS Chalkboard brand tablet when I present.  I use this
so I can make notes and work problems on the slides and move around the
room.  This worked great on my old laptop running Office 03.

The problem I'm having is that when I go into slideshow mode and try to
switch the cursor over to a pen, it still shows up as an arrow.  No
matter what I try, I cannot get the cursor to become a pen.  I click
the menu from the bottom, no dice.  I right click and use that menu,
nothing.  Always an arrow.  

Any thoughts on how to get my pen.  Many thanks in advance!
