I'm running .48 on Ubuntu and I'm a bit puzzled by the interface behaviour. some of the toolbars have moved from the top to the side of the window. Grabbing them and tearing them off works, but I can't get them to dock again. So I end up with a whole lot of free floating toolbars cluttering up the screen until I do a restart.

It must be something simple - put me out of my misery please!
