Tab through button objects

[ohmbru2]

I’m upgrading to Adobe Acrobat 7.0 (from 5.0). Some of my documents have many buttons which are hidden until the user clicks to reveal them. Most are almost as wide as the page with various heights depending on the amount of text. There are so many on some pages that they are on top of each other and overlap almost completely. In 5.0 I am able to cycle through these button objects with the Tab key. I have not discovered how to do this in 7.0. This is frustrating and will drive me to eliminate a convenient function for the user.

Any help is appreciated.

Thanks
