I just switched my form options from browser enabled to form filler and am taking it for a test drive.
I have a button that, when clicked, will email the active view inside an email message (not as an attachment).
This worked perfectly in the browser but not in the form filler.
An email pops up and has the from/to/subject/introduction but no form view.
When clicking this button in the browser there was a simple (sending data) dialogue and the email was sent without displaying it to the user.
