I have a ppt-file which for some reason does not have a Background object.
My file consists of 3 slides. The 2nd slide is very simple with a white backgground. When generating the dynamic content, the Slide objects BackGround property is null!!! (how can you not have a background?)
The BackGround property read-only so I cannot set it.
Here is the strange thing.
1. When I open my file, and change the background-color to black, the Background is no longer null.
2. It is possibly a Office Xp/ Office 2007 issue. When I open the file in Office 2007 and clicks "Save" it works. When I click "Save as", it doesnt work!
