Dear Anand Sri Thanks for your reply. The form was originally created in Adobe Acrobat Pro version 10.0.  A button was added to automatically open an email to send the form once completed. The command used was Action:On Focus- Submit a Form. This was linked to an email address using the command Mailto: email address. The Adobe Reader is version 18.09.14 and on a new apple IPad.  I’m only interested in the form filling PDF at the moment using an IPad we are using this for Quality Control purposes.  When I created the form originally and sent it to the IPad it worked OK.  After clicking the Mailto link a message appeared and gave the option to send as the original format or to send as a flattened copy to prevent further editing. This was then followed by a standard email window where further info such as photos could be added before sending.  The new version which I’ve updated to that is 18.09.14 no longer gives any option to flatten the document so I have a big problem that I need to solve if possible. Any help would be greatly appreciated. Regards Paul [personal information removed by moderator.  Please see https://forums.adobe.com/docs/DOC-3731] ... View more
