First the choice "all" is not seen by the widget when you choose it in the admin settings.
Secoundly, when you let it choose by users, the "and" (traduction of "all") appears in the result's url but it doesn't work !
In fact, this plugin is broken (see other posts since one year in this forum).

I have been using the plugin for nearly 2 years.
tried updating to the latest version about a year ago and it just stopped working so I had to download an older version and re-install it. Haven't upgraded it since then. I currently use version 2.2.2 which seems to work fine (I am on WordPress 3.3)
have to agree - this plugin appears totally broken - displays search button and clear all button, but NO drop-downs in widget bar.
shame - wordpress needs something like this for multi-selects.
