Well, I'm learning something new which is the whole idea . But, yes it looks like you are right about that. The only option to really make it work would be to upgrade to an 18F pic, which I've been told can support a high priority interrupt. In other words, it can interrupt an interrupt. Please, somebody correct me if I'm wrong about this.

What do you mean by no PBP code? Isn't TOGGLE a PBP command?

Also, where do you see that I'm clearing the interrupt flag twice?

That would be the best solution. I have to start working on that.
