Raspberry Pi Desktop - reducing the number of desktops

The G4KLX software image from Western D-Star comes preconfigured with 2 desktops. Operating through VNC I experience lots of unintended desktop switching which is very cumbersome, particularly since I don't need multiple desktops.

The number of desktops can be reduced in a number of ways:

Via the Desktop:

Openbox Config
Menu -> Preferences -> Openbox Configuration Manager
Desktop Config
Reduce Number of Desktops to 1

Via the command line (Terminal):

Edit lxde-rc.xml located in /home/pi/.config/openbox/:

nano /home/pi/.config/openbox/lxde-rc.xml

Find <desktops> section and within this section the line

<number>2</number>

Replace the 2 with a 1 and reboot.
