I did a fresh install of MPLABX IDE and IPE (v5.40).
IPE wouldn't work, and after much fiddling, I uninstalled everything and=20
went to an earlier version... v5.20.

Now IPE works, but when I plug in a Pickit 3 and try to connect, it=20
gives me a warning that the device's LVP bit is OFF but the tool is set=20
to LVP.  It suggests changing to HVP.  Note that no chip is connected, btw.

When I connect a chip (18F25K22), it detects the chip fine, but in=20
Power->ICSP Options, the pull-down selector for Program Mode Entry is=20
greyed out but set to "Use Low Voltage Program Mode entry".

I'm trying to understand what's happening here...
(a) Is it defaulting to HVP because the bit is *possibly* off on the=20
chip, and hence not letting me change that?
(b) Is it use LVP (because the setting says that) and not letting me=20
change to HVP for some reason?
(c) Or... ?

FWIW, I want to use HVP.

Cheers,
-Neil.
