Ok, so I am feeling quite ignorant...
I am running the latest Cyanogen Mod, I am overclocking my Droid, I use ROM manager and Clockwork Recovery. However, when I enter su into Terminal Emulator, I get a 'Permision Denied'.
Also, clicking the Ninja in my tray gives me a blank screen.
I have not installed busybox, nor superuser... is this the obvious missing link?
I have tried restoring to an earlier nandroid backup, but the same situation exists.
Any insights you can offer will be much appreciated.
