Office Enterprise 2007 is installed on two systems with Windows XP Service
Pack 3.

Computer 1: Office PowerPoint 2007 (12.0.6504.5000) SP2 MSO (12.0.5425.1000)
Computer 2: Office PowerPoint 2007 (12.0.4518.1014) MSO 12.0.4518.1014)

The problem I have is the Pointer Options menu (accessed from within a slide
show) does not work on Computer 1.

Computer 2 is able to use the Ballpoint Pen, Felt Tip Pen and Highlighter
tools. When I select those tools on Computer 1, the pointer stays as an arrow
and I'm unable to annotate slides.

Suggestions on this site for Office 2003 have been to install the
Handwriting Component under Office Shared Features. I don't see this option
on either computer.

I've posted on microsoft.public.powerpoint, but I haven't found a solution. Any other ideas?
