I'm also getting problems with the hot key assignment. I previously had Ctrl-Alt-X assigned, but now that isn't working and when I try to use that assignment it says it is "already in use". I then shutdown X1 after changing to Ctrl-Alt-Y and when I restarted it again said that "Ctrl-Alt-X" was in use. When I opened the options it was using Ctrl-Alt-Y which is still working.
Strange behavior.
