Something (I believe it's an Adobe registry setting) is not allowing the default e-mail client to open a new message from Adobe reader, but mailto links from websites open a new message just fine!
PDF fillable forms opened in a web browser (or downloaded and opened in Adobe Reader) are submitted via e-mail.
For months, everything worked great. When a user wanted to submit the pdf (with saved data) as an attachment in e-mail, they could either hit the submit button and it got attached to a new message with the intended recipient auto-filled, or they could choose Tools, Send Files, Attach to Email and the new message popped up, regardless of whether Outlook was open. (default email client)
This problem exists on XP machines running Outlook 2003 and either Reader 9 or X. It's sporadic. After uninstalling Outlook, reinstalling, and rebooting, it works for a day sometimes and then the problem is back.
Could the Microsoft .NET Framework 1.1 security update have anything to do with this?
