Problem making a 97 ppt slideshow viewable in moderrn viewers

[Aquinax]

Hello,

I have an important Powerpoint file created back in 1997 which I want make viewable again on modern machines.

I've imported the file in MS Powerpoint 2000 and then saved it in it so it can now be opened and viewed in Powerpoint 2013 (Office 2007 and up cannot open the file). The resulting file is rendered perfectly in all but one aspect:

The text of each slide appears wholly as a background shadow immediately with each new slide instead of sequential feed upon mouse clicks. This spoils the more interactive, progressive rendering of the slideshow. To illustrate it:

In the original slideshow you move from this:

to this

over a course of few mouse clicks.

Whereas in current viewers each new slide already contains all the text (in shadow font) which then is just being filled up by the original light colour:

Thank you, all ideas will be most welcome.

Thanks for replying on msofficeforums. I apologize for asking on two forums, the issue is rather significant for me. This is your reply in the other thread:

The shadow feature changed in 2007.

You will almost certainly have a shadow on the SHAPE with text. You can remove this in any version after 2007 and it should then work. If you want a shadow add it again to the TEXT

I noticed you have posted this same question in other forums. You should mention this and when you have a solution go back and let people know. Otherwise people could be working on your problem when it is already solved.
I've tried it and will leave a reply there shortly. Thank you again.

I was just asking that you SAY it is posted in both places so that people can check it hasn't been answered. I'm pretty sure it will be the answer - seen it many times!
