is only setting a partial number of config bits for that chip ,the bits that are omitted will revert to their default state , it may cause your [totally unspecified] problem, or it may be in the unposted code or both

Thanks for your help, Richard. Yes, that's the device. I'll post the code and a schematic. I was reluctant to because it's pretty long and I'm not sure I can fully explain all the things I'm trying to do.
