This isn't a problem with the plugin, but more of the way SM
stores information about the active folder. We store a list
of emails for the active folder, if you just opened a new
folder in a new window, you reset that list, and as such...
it'd be "broken"... So until we rewrite that whole bunch of
code (will be a whole lot), then don't open folders in a new
window ;)
