I've been testing out making forms in InDesign CC and as a simple test have used a couple radio buttons from the Sample Buttons and Forms palette (which seems to be completely void of sample forms, incidentally, but that's another matter).
When I export to PDF, the buttons are completely obscured by the square default cyan highlight and will only appear when I click on the area.
Am I doing something wrong? Seems like a no brainer, but I can't figure out what's wrong. I've even tried putting the button art and the button fields on separate layers. Still the same problem.
