Do you need to rearrange the buttons in the layout? If you just drag then with the Selection tool to move them. They shouldn't overlap.
If you want to change the Tab Order of the buttons or form fields you can set this in Object > Interactive > Set Tab Order. This is the order in which the buttons or form fields are selected when you're viewing the PDF you creat, and you press the Tab key in Reader or Acrobat
That's it! I can't believe I didn't see that.
Thank you very much!
Steve, I was working on an all pdf-interactive gallery slideshow within my portfolio that's 3 different mini photo gallery button actioned apps in one page and things went good until I added a title button thumbnail for each gallery [which revealed the gallery and it's thumbnail navigation arrows] and when my thumbnails opened up the actual sized images [when starting from title buttons] the unclicked title buttons would remain on top...I thought it was so trange that there was no way to arrange the buttons and it was frustrating that the Arrange panel had no effect. I knew it was a stacking problem but without your helpful pointer of the Set Tab Order panel I would've been rearranging visibility settings all night long. Thanks a million.
