If you have clicked on the "keypad" button in the last alpha version, the keyboard will show only a little grey shape and no keyboard anymore.

To reset it, you must open "config.xml" in NMC's folder and search for this:

Code:
		<keyboard>
			<dernier_mode>full</dernier_mode>
		</keyboard>

And replace with this:

Code:
		<keyboard>
			<dernier_mode>medium</dernier_mode>
		</keyboard>

Save and launch NMC, it's ready to go again

NOTE: this bug will be fixed in Alpha 2 (i must do the skin )
