Have you tried Activating the views?

1 click or tap on the screen and goto Desktop Menu (where you can add contacts /add widget and other stuff..)
2 Click or tap the Manage Views
3 select or deselect how many desktop you like to keep.

Note: those new desktop should display blank or black since there is no background on it. you will have to manually add backgrounds once u active those.


Hope this helps.
