I've had the 9400 for a few weeks now, it has the latest firmware but no prontoscript yet just plain old xcf.

Its been functioning fine but today all the hard buttons have started behaving very strangely. Some hard buttons don't work at all, while others perform the wrong hard button function. The touch screen seems to be working fine.

I've tried reseting it, disabling scripting, reloading the xcf but it's still faulty. Its not my xcf because I downloaded the default Philips xcf and its got the same behaviour.

Anyone seen this problem, I think the unit may be faulty but its a real problem because I brought it in the USA on a recent trip and I live in New Zealand.
