"Go back on roll over" interactive button state checked/greyed out
I was working on an interactive project and found that the "go back on roll over" option becomes turned on and greyed out so you cannot un-check the box when adding an "upon release" action to a button. I initially could NOT figure out why this was happening, and it was totally screwing up my on-click actions in my project.
Eventually, I think I figured out that it seems to happen when you create a button, add an "on roll over" action and check the box "go back on roll off", then create ANOTHER action (like "on click"), and then DELETE the original "on roll over" action. If you go and look at your "on click" or "on release" action you created, the "go back on roll off" box is showing and is checked and is greyed out so you cannot edit that option.
"Go back on roll over" seems like something that should be SOLELY associated with roll over actions, and should be disabled as soon as you delete/remove ANY roll over actions you have created.
I finally figured out how to fix it, which involved adding an additional roll over action to the button as well, deleting my original "on release" action, deleting the roll over action, and then RE-adding the "on release" action again.
It took me about 30 minutes to hack this, but it's obviously a problem.
You should really consider working on your interactivity problems, as more and more people are using InDesign for digital publishing, especially those who are working on print projects that also need to be converted into digital formats.

Had the exact same problem! Thank you for being one of the only resources I could find to fix it!!
