I just installed Ubuntu 11.10 yesterday alongside Win 7 to try it out (and maybe get rid of Win). I liked the workspace concept a lot, dragging a window into another workspace form the four-workspaces-view. Then after some installing I had a crash - Ubuntu would not start any more and I hat do go through the Ubuntu setup from Windows again (three times until I got rid of the crash problem). But ever since the drag and drop function in the 4-workspace view does not work any more. I googled a lot, installed unity and compiz config, changed hundreds of settings but can't get it back. everything else (shift-alt arrow and right clicks on the menubar) work, but i can't click on the miniaturized windows in the workspace selector any more.
