Thanks for the replies. I found the "PIC18 CONFIGURATION SETTINGS ADDENDUM" file, and that cleared up a whole lot, don't know why I didn't find it before ! :) Still getting on the MELABS programmer, no change in the configuration though. Is there another way I can verify what the actual config is? I'll drop an E-mail to ME labs, and ask there, but thinking MPLAB should have a view to the actual config.
