Configuration bit programming in ISP in PIC16LF627A is incorrect

Hi Neil
got a bit of a weird one, If I program the PIC16LF627A via the zif socket.... all is well program works well
when I do so via ISP with the same file, programmer confirms verify is good!, but chip does not work!
so I put chip back in the programmer ZIF socket and do a verify... It says its different! the config bits at 2007, but that's the only error, its programming the rest of the chip fine
so that's why the chip no longer functions!
L2539: ADDRESS DEVICE BUFFER
L2540: -----------------------
L2541: 00002007 3F90 2110
the config bits are set the same (using the same file) when programming ZIF and ISP (and LVP is set)
what am I doing wrong? I have the programmer to program all areas, (program, config and eprom) its just the config bits that don't match!
thankyou
