OK.

Please forgive my slowness, but I'm not sure I follow you.  All my timing is
based on a 1ms Timer0 overflow interrupt...the button check routine just
reloads its own counter with d'73' every time it's called.  Are you
suggesting I cobble together a little delay routine based on processor
cycles and use _that_ to call the button check?

Good question.  I believe they are.  My initialization loads INTCON with
b'10100000', which should enable Global Interrupts (GIE) and the Timer 0
overflow interrupt (T0IE), and disable the Port B interrupt-on-change, the
RB0 external interrupt, and all the peripheral interrupts (according to
DS30292C p20).

Please keep throwing me these questions...anything to help me sort this
blasted thing out.
