I recently encountered something similar to this. I have an inserted AS2 Flash built animation. Simple stuff. It wouldn't play after publishing. It would play in PowerPoint preview however. Strangely, if I played it in preview the last frame was visible when published.
I use MS Office 2007. Initially, the original presentation was a .pptx file. When I saved it as a .ppt file and published, the animation played just fine.
The problem began after Flash Player 10.1 was released. I don't know if that actually had anything to do with the issue.
thanks for that. Will check it out.
We just recently ran into the same problem. From our review, iit appears that the flash objects are not picked up in the viewer.xml file when they are published. Anyone has any ideas as to why the .ppt format will work and the .pptx format does not?
