I am working in Word 2007 and have inserted several controls (option, drop-down, text). After protecting the document, all 3 controls work for me. However, when another user attempts to fill out the form. The only controls that work are drop-down & text. The option button does not allow for them to select. After attempting to problem solve, the only thing that I can see as being different is that the option control was inserted using ActiveX control while the other two (drop-down & text) were inserted by using Legacy form. There doesn't seem to be an option control choice through Legacy Forms.
What can I do to get the Option control to work for the other users?
