Excuse me if this is the incorrect forum. I received a fillable PDF form and, of course, filled it out. I could print it and save it on a Windows 7 machine with it opened by Foxit Reader. The Document's properties were all "allowed." But, to make sure I can create a form using Acrobat X and distribute to computers running (most likely) Acrobat Reader on Windows XP and 7, etc., I took the form to a machine running Ubuntu 10.10 and opened it with Adobe Reader 9. Immediately, Reader notified me the form could NOT be saved and to PRINT a copy. The document's properties were a mixture of allowed and disallowed. My plans are sunk if I can't distribute the form from a Web site. What's my problem?
Note that documents that have been enabled with Acrobat have certain licensing restrictions. In short, you may use data from no more than 500 instances of a form that has been returned to you (including hard copies) if you distribute the document to more than 500 recipients.
