Problems with Redemption & RTF

Okay... I am trying to prepend all outgoing e-mails with a security identifier. I would prefer this to work with Outlook 2000 and newer but the biggest requirement is for it to work with Office 2007. Now I have 95% of this functioning, but there is an issue where everytime you send from rich text it doublespaces your autosignature. The other issue is if you right click a document and go to send as -> email, the prompt does not appear and gives an error about a modal dialogue. I have tried making the form non-modal but the results were unstable (the form keeps flickering behind the message).

Anyone have any ideas?

The form I have created is a simple, small form with 3 radio buttons designating the 3 security identifiers that can be chosen, with a send and cancel button once you've selected an identifier.

I am using the following code developed in VB6 using redemption .dll.
