I created a pdf with text fields in Acrobat Pro 9. I sent the document out to the various people that were responsible for filling them and when they returned them to me, I cannot see what they have typed when I open the pdf unless I click the text field where I know type should be, then I can see it. But, it disappears when I click away. I tested it with several people and if they open in Acrobat they don't have an issue and can see all text, it only occurs with people who open the pdf in Acrobat Pro. I'm certain there is a simple solution to this issue but I admit I'm stymied. Thank you in advance for any help.
This is a well known problem casued by the Preview application on a Mac. In short, it causes extensive damage to PDF forms when it saves them. For more information, see: http://kb2.adobe.com/community/publishing/885/cpsid_88564.html
