I don't see any need to wait that long and swap for a Mark 2 player - in any case that wouldn't prove anything, the Mk. 2 buttons are exactly the same, but the PIC software has been tweaked to work around the problem.

We have lots of Mark 1 spare parts. I'll choose someone that is experiencing significant problems with the bug and invite them to return their player (at our expense of course) for a display board swap. We'll test the new board thoroughly before it goes out.

If the client still experiences problems it must be something related to their specific usage patterns. If the problem goes away, then we have our answer and will look more closely at the known-defective board to determine a fix.

Any volunteers? I need someone who experiences the bug often, and preferably in Europe to minimise shipping delays.
