@Alex - that solution doesn't work. I tried to show you what happens by giving you access to a guest account. The search can be made to work properly, but if you use that fix, then members can never edit their accounts again - if they do, then "not selected" will be selected as an actual value. The Trac on this was incorrectly closes, which may by why this serious bug has gotten no attention. If you have a temporary fix for 7.0.x I would certainly like to hear it.
