[imp] IMP 4 and clicking on "From:" e-mail addresses in the e-mails list view

[imp-archive@cloud9.net]

How do I make IMP 4 have the old behavior of when a user clicks on either 
the From: address or the subject of an e-mail they go to read the e-mail 
as opposed to the current behavior in which one clicks on the From: 
address and a compose window pops up?

Is it $conf['mail']and then something?

I can't seem to find it anywhere.
