9XR Keypad and Throttle Issues

[GoogleCodeExporter]

The 9XR has new soft keys. These keys have a tendency to do a few funny things.

1.  Double Bounce.
When you press on the button, the software will read the value of the digital 
pin. Unfortunately the signal can sometimes "bounce" between high and low for a 
few milliseconds giving the appearance that the button has been pushed multiple 
times.

This issue could no doubt be detected and fixed in software.

2. Directionality Misfire.
The keys suffer an issue in that when you press 'down', it can sometimes also 
trigger a 'left' or a 'right' input.  This is no doubt also due to the soft 
nature of the pad.

A fix to this may be to detect the first input, then ignore subsequent inputs 
for X milliseconds.  This may well then only pickup the correct key.. and then 
ignore the erroneous ones!

Received a 9XR yesterday. DBLKEYS seems to me mechanically impossible to 
achieve!

I am afraid I can't do anything, the only solution is with the switches 
replacement
