PIC18 interrupt handler, where to save W etc?

[Bruce]

Is there a reason anyone can come up with for using only Low Priority Interrupts?

I use low priority exclusivley unless I have more than 1 interrupt, and one 'or more' needs priority over the lower priority interrupt task.

If you only have 1 interrupt enabled, I can't see why making it high priority VS low priority would be of any benefit!

Consequently, DT_INTS crashes if you try to only use LP ints

Yikes. I haven't used DT_INTs much with 18F types, but that's good to know. What causes that to happen?
