Sounds a bit like magic...  I'll toss this over to the team, but I have a hard
time believing that this has any real effect at all.

v4.12.12 is mainly for the 18Cxx2 support and MPLAB-ICD NT compatibility and
overall ICD improvements.  It has a few known glitches, one in the __config
directive in MPASM for the 17Cxxx family, an inability to "fill range" with the
Modify dialog in simulation mode, and an annoying message that comes up
sometimes asking you if you want to rebuild the project.  Unless you've got
MPLAB-ICD or want to explore the 18Cxx2 architecture, I'd recommend sticking
with v4.12.  Full production release of v5.00 comes out in December with these
bugs fixed, some new parts support, and a major system overhaul of the on-line
help, with a general clean up of the system.  Some of these features can be
seen in v4.12.12, but v5.00 will have a lot more, including MPLAB-ICDE 2000 NT
support.
