The PC at the McH desk is having intermittent problems accepting keystrokes for entering the password. This seems to happen only at startup. If it happens to you:
1. Restart the machine - holding down the power button for 10 secs will do it.
2. Make sure the numlock is on to use the keypad, OR use the number bar at the top of the keyboard.
This should remedy the problem. Please enter a ticket if you try this and the problem continues.
