I've created a form in LC ES2, and included an email submit button. When I open this form in Acrobat Reader 10.1.3, click the submit button, and specify "Desktop Email Application," as opposed to the "Internet Email" option, no email is generated, Reader locks up and requires force closing. This happens also with Acrobat X Pro. With both programs, it happens (1) when the form is Reader enabled AND when it's not, (2) when I use an http submit button with a submit to URL of: mailto:self@univ.edu, and (3) when I use a standard button, with control type "submit" and a submit to URL of: mailto:self@univ.edu.
I AM able to save the form in Acrobat Pro and in Reader (when rights are enabled), I just can't email it.
