PIC18F4550 to 18F4553 Comm Issue?

I defiantly would have mentioned Pickit vs bootloader if I thought that would have anything to do it. I thought they would program what ever I had configured. Sounds like that may not be how the boot loader works though? Good to know.

Thanks

It depends on the bootloader you're using... some will, some won't, so it's worth checking.

It's usually a good idea NOT to allow the config to be reprogrammed. For example, if you goof up/change the osc setting you can easily turn your board into a brick.
