Oh well, HTML-Mail... I always said they are evil (I still avoid 'em whenever possible - enriched text was the speced way to go (but has any mail client besides emacs and mullberry ever included it? (At least M2 could display(decode) such mails if I remember it right))), could be a drawback - but what the heck' if at least on Windows the Blink API doesn't allow for an added module to use it's rendering features outside the browser part, then one could easily adopt to using the IE object via OLE/DCOM/COM+/Net-Framework (whatever the "best" solution is nowadays?) for rendering the mails inside the Clients Window (How do you think e.g. GoogleEarth handles it's Web-Frame on Windows (Not sure if that one still applies on the current version))...
