Way to get imp to open when a mailto: link is opened

[Cory Merritt]

Does anyone know of a way to get the Compose.php3 page from IMP to open when 
someone clicks a mailto: link on a web page.  I have figured out how to make 
the correct registry entries.

What I need now, is to figure out a way to go directly to the compose.php3 
page, and pass the address from the link the user has clicked into the to field 
on the compose.php3 page.  The other problem that I am working on is figuring 
out how to have the user logon during this process or attach to an existing 
session.
