I recently installed Xubuntu 14.04 and I noticed that it had Ctrl+F1...etc assigned to switch workspaces.
This is very annoying since Ctrl+F4 is for closing tabs in my browser and I use it a lot.
In old XFCE in 12.04 I had it set to Super+1...etc to switch workspaces.
So I went to Settings -> Window Manager to change it. I changed the keyboard bindings to this:

And it worked, till I rebooted.
Once I rebooted the next day my keybindings were right back at Ctrl+F1 even though the settings screen shows different. This screenshot is from right now, and those key bindings aren't working. If I press Super+2 nothing happens, if I press Ctrl+F2 it switches to Workspace 2. Even though, as you can see from the screenshot, it is set to the super key.
What gives with the new XFWM?
