ok, I did an upgrade of my test machine from 4.2.3 to 4.2.4, and sure enough the GUI behaves the same as my production, that is if I click my location from the dashboard the gui shows all the devices.
Seems like a bug to me, can someone confirm this ?
Next up I'm going to try a fresh install of 4.2.4 and see what happens on the fresh install.
Tushar.
