I have the follwing entries in my rc.xml:

  <keybind key="C-F1">
    <action name="desktop"><desktop>1</desktop></action>
  </keybind>
  <keybind key="C-F2">
    <action name="desktop"><desktop>2</desktop></action>
  </keybind>
  <keybind key="C-F3">
    <action name="desktop"><desktop>3</desktop></action>
  </keybind>
  <keybind key="C-F4">
    <action name="desktop"><desktop>4</desktop></action>
  </keybind>


When I switch from a desktop with applications on it to one with no apps it only
allows it the first time. And it doesn't work.  I can switch between desktops
with apps forever and between ones without apps forever but when I mix between
ones with apps and without it only works for the first switch.
