Hi Ric,
It can be done with a macro in Powerpoint, (search on Mouseover at the Powerpoint FAQ at
http://pptfaq.com ). However, your other
post on Expression Web may be an indiciation you're looking to do this when PPS files are viewed via a web browser. In that case
you may want to use the link below to also post in the Powerpoint discussion group with an explanation of the effect you're trying
to achieve.
=============
Is there a way to create a "pop-up" in a power point presentation. I would
like to use the mouse in my presentation and when I hover over a specific
word a "pop-up" appears in a call out format that contains such information
as a definition for the word being moused over.>>

Please let us know if this has helped,
