Hello

I'm been using the chbox plugin from some time without problems, until I upgraded to 0.8.4.

Now the chbox selector appears in each mail line, but I can't perform the "Select all, Unread..." operation, because the menu to do so doesn't appear when I click the icon...

It's due to a javascript error in chbox.js: 

Uncaught reference error: rcmail_ui is not defined

Here it appears: 

function rcmail_selectmenu() { 
  if (!rcmail_ui.popups.selectmenu) 

Has this JS object disappeared or changed in the last version, or maybe it's some other kind of problem??

Thanks in advance
