LOL Adam :-)

Following this thread with interest here.  I've experienced my fair 
share of "signal integrity" issues with digital circuits, (albeit 
usually with faster signals,) but don't think I've ever had something 
clocking on the wrong edge before!  In my experience you usually get 
"double clocking" or "multiple clocking" of digital circuits if there is 
ringing or noise on the clock signal.  For example I've had counters 
that count up in twos, or LCD screens that display every character twice 
because there was bounce on the data strobe line.  This clocking on the 
opposite going edge does seem particularly unusual to me though.
