I started posting about a problem I had with KeyPad, where one key was not working, but just typing it up gave me the clue, so I will just mention it in case others have the same problem.

The unit is a remote control, using VirtualWire driving the transmitter.  I reallocated the default transmit pins ( data and PTT ) to 15 and 13 to suit my layout.

Being only a transmitter I completely forgot that VirtualWire also allocates pin 11 as the default vw_set_rx_pin, which I had as set as one of the columns in KeyPad.

Reallocating the vw_set_rx_pin to a spare pin cured it of course.
