Makes me wonder if the two bits really change at the same time.  If I had 
this hardware in front of me I would try a loop that polls and stores the 
state of the bits (in RAM).  Then peek at the results to see what 
happened.  Kind of like a graph, but very quick and dirty.  Have to adjust 
some delay in between samples so the event fits in RAM.

Another thought is that it takes some time to wake from sleep, and that 
could affect your success rate (as opposed to the theory that the 
sleep-int-wake method is actually correct).

I know it's all working now, but, well, we /are/ engineers and can't stop 
wondering about it.

Anyway, good thread about another PIC quirk.  I shall mark it and save it.
