Is that master page applied to all the pages? Have you checked the layering to see if another layer is higher in the order? What kind of a button did you create? What version of InDesign? What operating system?
yes, the master is applied to all pages...they are go to next page/go to previous page buttons. no layers are covering anything.. the weird thing is that one time I exported it and all the buttons showed up and then I exported it agian and buttons only appear on the first few pages. Very strange. Indesign CS6 on a MAC running OS X 10.8.3
thanks for your help
Did you end up resolving this issue? I'm having the same problem and didn't want to post if you'd managed to work it out.
The weird thing is mine is on a document that was originally created in CS3 or 4. It's been revived for a new edition, and the buttons used to work perfectly under the old version, but now they're behaving exactly as you describe.
Any tips would be much appreciated.
