4-Line LCD and 18F4620

[Bruce]

The only difference between the two codes is the config setup

This would be part of the problem at least. The 18F4620 has A/D inputs on several
port pins you're using to control the LCD.

RB4 is AN11. RA0 is AN0. ADCON1 = 15 disables A/D so you can use these pins for
digital I/O.

I've never seen the internal 402 error, but a re-install should take care of it.

Tried a reinstall , uninstall and install same-o, same-o. The question I have is: Is error 402 a lock up event meaning the programmer is bad and will need replacement. I hope MeLabs likes me. I will try turning off the comparators later. A positive side of all this is I had time to learn more about the drawing program in Eagle.

I've never seen the 402 error. I can only find referrence to it in the PM assembler text. I don't think this error has anything to do with the device programmer, but I would for sure contact MeLabs on this one.
