That was indeed the problem - my app has now been changed to account for
the new API and it works very well (the detection seems much more reliable
than 0.4.5).

This is what I ended up with for the mapping to emulate the single column
I'm interested in - the defaults only go from A to D (why has the rest of
the array been changed to NULLs?).

KeyMatrix_4_1=A
KeyMatrix_4_2=B
KeyMatrix_4_3=C
KeyMatrix_4_4=D
KeyMatrix_4_5=L
KeyMatrix_4_6=Q

All done :-)
