I have encountered exactly the same problem that you are describing.
The keyboard was purchased about a month ago to replace another extended
keyboard which I gave to my sister.  The old keyboard did not display
this problem, but the new one is prety consistent as you are describing.
It also generates the same garbage characters when typing "o,p".
(And "ou;" instead of "out", but that's less frequent.)
I have not tried any other key combinations, but since
the "," and the "M" keys are next to each other, I would assume
some problem with the contacts in the keyboard and not in the software
(inits, system, etc.); I am using a MacII 6.02 and lots of inits.

Has anybody else encountered this strange behavior???

Any solution???
