Twenty minutes before show time, my PowerPoint 2007 presentation (Sorry kittens) was possessed. I tried adding a drawing item to an image and nothing happened. I couldn’t get the the image to display in the normal slide view. I couldn’t fix the problems, so I gave up and went with what I had.
Later I tried to figure out what went wrong. As best I can tell the themes/layout control data had been corrupted. This particular presentation started with a corporate theme as PPT 2003 and had round-tripped between 2003 and 2007 a few times.
Evidently, a few times too many.
Setting a theme on a slide didn’t fix it. The fix was
- To to View – Presentation views – Slide Master
- In this view, choose Themes and apply a theme
- Go back through presentation and fix everything up
I had to make do with a standard PPT 2007 theme, but I could again edit my presentation.
