In this case, when pressing the '4' key repeatedly to test it, the symptom is to get a few '6's and then the calculator goes dead - i.e. the display is dark and no other keys work. Switching off and then on again brings it back to life, though.

But you could be right about debouncing - I just picked the calc up to see what it would do - it had been behaving itself - and this time I got two '6's and then it died. On repeated testing, I'm not seeing two - sometimes three? - '4's or '6's being entered in response to one keypress. And the problem seems to have spread to the '5' key as well, only not as bad.

Sigh. No rush; I'll wait for the DEOXIT to arrive, and then see how it responds to that.
