Hi Steve -

Thank you for your reply and I apologize for taking so long to respond -
shows how nutty the workplace has been lately.

Anyway, to answer your questions, I am using Adobe Acrobat 6.0 Standard for
the PPT to PDF conversions.  I did not change the proportions of the original
slide, and I kept the width & height measurements the same in both.  

I did not try ungrouping the graphics, as keeping them grouped seemed to
keep them from movning around. as much.

One discovery I made was that the person creating the poster used text boxes
on top of text boxes - i.e., instead of drawing a shape (like a box) and then
typing her text in that, she made one text box filled in with a color, then
another text box on top for the actual text.  In this case, everything moved
around during the conversion, and some elements hid others.

Thanks for your help.

Patty
