We have a problem with 1 of our Promethean boards. It was all working fine, then 1 day just decided to ignore the pen, everything looks fine, the board is recognised on the PC and appears to be working fine, the power light is on the board and everything looks ok, but when you move the pen on the board nothing happens. I've tried 3 different pens and still nothing. Anyone come across this before???
Any ideas would really help.
