Yeah, and how!  I'm disgusted with my ICEPIC.  I'm using it to
emulate a 16C620, which has brownout protection on-chip.  The
emulator DOES NOT have brownout protection on-chip.  Whenever my
application fires a relay, it makes a glitch that sends the emulator
into LaLa Land.  it will do things like not increment on INCF, ignore
watchdog timeouts, or step through comments as if it was executing
code, stuff like that.  If it's not the brownout problem, then it's
probably some other noise related glitch, cuz it mostly happens
whenever a relay fires.

So far I have not found a solution.  Apparently the PICMASTER has the
option of running on it's own internal power supply, and also has
better shielding to the probe.  I'm begging my boss for a PICMASTER
for christmas.
