Hi Barbara,
Thanks for working through this. I can't test it as my computer doesn't have earlier versions of ppt.
I have tried a few workarounds today on the competencies pptx. The results might be of interest to others too.
1. I found a setting to "optimise media" for presentation on another computer and resaved the pptx. This may work. (???)
2. I saved it as a Windows media file and an MP4 video. These work well. They maintain the animations and you can control the location in time but you can't get a response to a click. The downside is that the file sizes are 62 and 78 MB each. If necessary I could put one in Dropbox for downloading.
3. I used iSpring (a recent Giveaway-of-the-day) to convert it to HTML5 format. It seemed to change the size and so moved the text in the rectangle to the left and chopped the side of the rectangle off. This is very odd as the rectangle was actually a textbox so should have all stayed together.
4. Finally I saved the optimised media version as a macro-enabled slide show. You can click your way through the ppt (.ppsx?) but if you hit escape the show closes. In other woords, you can't stop it.
I'll upload the optimised media pptx file (attempt 1) with this post. If someone who has 2003 PPT with the 2007 reader/extension could try it and let me know if it works I would appreciate it. If it works I can upload versions that everyone can use.
Thanks a lot
Ian
