It's a known problem (at least in this newsgroup) with PPT 2003 and Adobe
Acrobat Reader 7. I think Microsoft blames Adobe and Adobe blames
Microsoft, and we're caught in the middle. Check out "Use ShellExecute to
sidestep certain linking problems" from the PPT FAQ:

It has a solution, but it doesn't look pretty (I've never tried it
because I'm still sitting on Adobe Acrobat 5).
