Submit by email button fails in Reader

Okay, the perversity of this error is getting to be too much.

My objective is to have a submit button on the form that will send the filled-in form as a pdf to a designated email address when the user is filling out and submitting the form from Reader.

Seems simple enough. Using the default email submit button doesn't give the Submit tab in the Object window, so you can tell the form to submit as a pdf to the end user.

Of course, taking the other path and using a button with the Submit to URL set to mailto:*****, using XML data package as the Submit As and pdf selected under the include....... that should solve the problem. Problem is that the submit works perfectly in this version if the user is in Acrobat Pro, but if they are in Reader and submit the form nothing ever happens if they hit the submit button.

Tried resetting the Submit As field to pdf and then to XML data to see if that worked, but we get the same error - the submit button does nothing in Reader, but works fine in Acrobat Pro.

Went back to the original file and made sure the fonts were correct and there was nothing odd included in the Word file, re-exported the pdf and built the form again form scratch. Same results.

Tried building the form in Acrobat Pro without using Designer, and that just results in an Operation not Allowed error when the user tries to submit in Reader.

So what is the obvious point that I'm missing here? I'm yearning to submit this form to the nearest trash bin....
