I'm using Microsoft Outlook 2002 (aka Outlook XP) and whenever I create a new message or reply I get a security warning. What can I do?

(Resolved in 2.2.0)

This was a known issue in the addin's signature insertion engine that was fixed in the 2.2.0 release. The only known workarounds were either to disable signature insertion or to update to a different version of Microsoft Outlook (both 2000 and 2003 and later did work).
