[imp] MIME viewer download

[Chris St. Pierre]

In the thread at
http://groups.google.com/group/mailing.www.horde-imp/browse_thread/thread/c8e595e0a49ae2b3/82f0cbb5af8d494c,
Michael notes that "Clicking on the filename *should*, if a viewer is
configured, open up a HTML-rendered viewer, not display the file.  For
files without a MIME Viewer, this link should be identical to the
download link."

On my Horde 3.2/IMP 4.3 install, that is not the case.  For files
without a MIME Viewer, the filename is not a link at all.  How do I
get it to Do The Right Thing?

Thanks!
