I'm not sure how this is happening, because according to bug 26201, we don't
even associate *.eml files with Thunderbird.

Wilson Lee: the Internet Options "Programs" settings do not actually affect the 
'default client' setting, which controls the MAPI setup.  Set Program Access & 
Defaults (from the Add Programs Control Panel) should make the settings, and if 
I'm recalling correctly, so should the Tools menu item you mentioned from 
Outlook Express.  

I haven't gone back to play with this for a while, but the only times I've had a 
problem getting one client or another to properly register itself was when I was 
logged in without Admin privileges.  (Even that has been inconsistent.)  
However, you can't even run SPA&D without Admin privs, so it seems you know 
about this already.

If you're willing to spend the effort to help debug this: install a copy of 
RegMon   <http://www.sysinternals.com/Utilities/Regmon.html>   and create a log 
of what happens when you run SPA&D to set Outlook as the default.  Attach that 
log to this bug (use the Create New Attachment link above).

Adam, that comment actually doesn't apply to this at all; but see bug 242959.

xref bug 254262.

Since it appears I have to spend money to decode a .RAR file, I'm not going to 
look at that log.  Maybe you could try compressing it in a more widely accepted 
standard?

Reporter, does the issue still occur in the latest supported Thunderbird version 2.0.0.12 or trunk nightlies?
