We recently upgraded to Win 7 and to Acrobat 9 (didn't upgrade Office so cannot comment on that). The only issue I have found (and I can only assume it was
due to the OS upgrade or the Acrobat upgrade (or both)) is that I lost use of my Preview tab. In order to be able to preview a form now in LiveCycle, I must first open an instance of Acrobat, otherwise I don't even get a Preview tab. Also, the preview doesn't show up in the Preview tab...it actually opens in Acrobat.
Weird, but I'm getting used to it.
