you sure it does nothing?
per default it will shot the whole screen after 60 seconds and save it to /home/user/desktop.
Else use any other screenshot-application (i used ksnapshot for a while, but there might be others ).
you could also try unloading and reloading the screenshot-module (open the root-menu with a left-click on the screen or hit the window-button,then settings, modules).
