I'm an idiot and I don't know why! - CCP1_INT

RB3 CCP1 input is an ST type, so it needs 0.8 * Vdd to meet the logic 1 input threshold.

I can't really tell from your schematic, but it looks like you might have a voltage divider?

5.00v on Pin3

Hmm ... should work. I just tested it with the older version of DT_INTS-14 & ReEnterPBP.

Are you using the latest version? I haven't tried the newer rev yet.

[Cobra_Phil]

I'm using version .93 Beta DT_INTS-14
and version 3.2 ReEnterPBP.

Using the same here, but tested it on real hardware with a pull-down holding RB3 low, and
switch pulling it high when pressed. Works 100%.

Is RB3 being held at ground until you press the switch?

Thanks Bruce for the feedback. I'll try to figure out "Whats Up With That"...
Only wasted ~ 9 hours on it.....

Sorry Bruce, didn't see the last portion of your post. I assumed since it worked for you, it was a problem with the simulator. The simulator does show .02v when the button is not pressed and the rest of the inputs work correctly for the other interrupts. I guess I'm going to have to what for the real circuit board to arrive for further testing.
