Okay, sorry, traveling again and just got back to my computer. The suggestion I believe was to add the number 2 after TextFrame on the one command line. I did this and when I ran the macro it returned an error as follows:

Compile error:
Method or data member not found

and it highlighted the command .Color = vbBlack.....only the .Color was highlighted

I removed the number 2 and it ran correctly but again did not remove the shadow.

As for the file, I have just created a sample of 4 slides, each with different size text, different font, shadows, etc and the macro works on everything except the shadow still.
