I have a PDF form that I created in InDesign and Exported as a PDF and generated form fields including submit and print buttons in Acrobat 8 Pro. I then enabled usage rights and distributed the form.
It seems that when someone opens the form and fills it out using Adobe Reader 9, everything works, but the submit and print buttons that I added to the form drop out. At least the image does. The button itself seems to still be there, you just can't see the image for the button.
Has anyone run into this situation?
