The new PowerPoint 2007 is just wonderful! It really makes the task of creating a presentation easy and fun. Pity you can’t say that for the task of sitting through most of them!
If you don’t like the Office Theme which is the default, you can easily make any theme your own. Open the Theme gallery on the Design tab and right click the theme of your choice, choose Save As Default Theme and every time you start PowerPoint that’s what you’ll see. Neat huh?
