U80 Works when Programming, Glitchy when Debugging

So tech support said that I need a programmer cable shorter than 12", no resistance in series with the ICD pins, and a 47K pull up resistor on MCLR. They said that the debugger is continuously communicating with the PIC during debugging --- I am not sure if that is 100% correct, but I will give them the benefit of the doubt...

Anyway, I did everything they requested - my programming cable is 10" I have zero ohm jumpers on the ICD lines and a 47K pullup on the MCLR pin... The target still won't start the first time you press GO... The have to PAUSE and go again... Then the target stops randomly, and hitting PAUSE and GO causes it to continue where it left off...

What's with the U80... I wish I still had my old programmer... This one seems so glitchy in comparison.

I've also had issues with debugging with the U80, fortunately we also have several U64's that I can fall back to; so, I haven't tried many troubleshooting steps.

Programming with the U80 is generally flawless, though.

One thing I have noted is that if you use "target power" instead of letting the U80 supply power, it seems to work better in debug.
