Hmn.  That's bizarre.  Are you saying that the 18F452 doesn't drive
the display right, but the 16F877 can?

Could that hex file have become corrupted?  I find it hard to believe
that one line would work and the other wouldn't if the display is okay.

Oh well.  $9 from Digikey, if that is truly the problem.
