If I take an existing form that was created in Acrobat 7 Prof and open it in Acrobat 8 to edit form fields it crashes when I try to choose a tool. I have checked Adobe site and their list of possible OSX fixes - tried them all and still crashes. This new version of 8 is worthless to me. Help please
Contact the author of the version 7 PDF and find out if the form was developed in LiveCycle or Acrobat. You can not edit a LiveCycle form in Acrobat.
Check the security settings for the form and its other properties. You can not edit a form if it has certain security settings that prevent editing. Make sure the form was developed with an authentic version of Acrobat and not a clone.
