12. Allow server-side sorting : true
rg=on
php 4.3.5
squirrelmail-20040510_0841-CVS.stable.tar.bz2

how to reproduce it:
1. Open some folder(i use INBOX.sm) and start
navigating through messages with next|previous links
2. Use left frame to open other folder (i use INBOX) in
new windows
3. Get back to previous windows and use next links one
or two times and see how links become disabled or you
get message was removed error.

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 ;)
