Thanks Hani,

Your saving comments seem important. I did not even think about the saving end. I just saved the doc when the prompt came up.

So I need some guidance here.

Checking the finder, I see:

"MS PP presentation" as the saved, in pptx

I then tried to take that doc and "save as" in "MS PP slide show," in ppsx.

But it was the same size.

So -- do I have to re-do the entire presentation? And start from the beginning with new slides and save from the beginning as a ppsx???

Or, what else can I do?

From where I am now? changing the save as into something else . . . or even one of the other saves . . .

Thanks, Roger
