Thanks again Dan.  I did no that however, I am running a LCD display on
ports RB0:RB4 and I had read some documentation that some LCD do not like
the weak pull ups.  Anyway, I was having problems with the display and
disabled the weak pull ups.  I enabled the weak pull ups and the display
still works fine and now the interrupts work as expected

Thanks again for you help.
