Switching workspaces in XFCE issue?

view full story

http://askubuntu.com – I disabled the applet for desktop workspaces in my xfce panel(well I actually removed the panel all together), but now xfce seems to think my 4 workspaces are side-by-side and not splayed out, so the shortcut ctrl-alt-'up arrow' and ctrl-alt-'down arrow' dont work but the left and right arrow ones do. Any idea how to fix this without re-enabling the panel? I prefer using the cairo-dock as a panel substitute for those who demand a reason. (HowTos)
