Animations that worked in PP 2003 but will not work in PP 2007

[carbuthn]

I have made several piping flow diagrams, each slide has a system drawn on
it. When a button is clicked the linked animations shows the flow path that
the system liquid takes through the piping. The slides worked fine with
Powerpoint 2003, but nothing happens on 2 slides out of the 15 that I have in
the presentation under Powerpoint 2007. Has anyone one run into this problem?
Do you have a solution?

Also, (in a different presentation) I have used a lot of macros to make a
mini simulator, the relay and contact etc. have been named c1, c2 and aux1.
The macros would not work in Powerpoint 2007 until I used the uppercase
letters i.e. slide210.shapes("C1").visible. "c1" will not work. Why did they
make 2007 case sensitive?

Thanks
Chuck

Thanks Steve, I will be changing to tags on the new presentations, I have
corrected the old ones with a search and replace similar to the one you gave
me.

The second problem seems to have gone away after a re-boot of the computer.
