Why in the world would you want it to work on a mac?

You have obviously not used a MAC recently. I am typing this on my MacBook Pro. I use CoffeeCup programs on Windows on this Mac. It would be much easier if the CoffeeCup programs ran natively on a MAC. Many of the MAC slide programs offer amazing graphics and skins but they are not as editable as the Coffeecup programs. I specifically use JukeBox and Photogallery -

see http://www.trishandphil-music.com/TCAN032607.html for an example.

Yes, yes - Coffeecup for MACs!!!
