I see what you are saying, however what I had planned seems like it should have worked.

Nope, I was jumping the gun. Here's what I am doing:

red shape. add dropshadow. export as interactive pdf (iPDF) = maintains drowshadow

red shape with dropshadow on a layer above a light grey shape layer. expost iPFD = maintains dropshadow

red shape with dropshadow on a layer above a light gray shape that has been converted to a button. export iPDF = not layer effect.

Nuts!

David, Thanks, that is exactly what it is. Brilliant! Thanks for the link. Productivity here I come.
