Thanks. I can't see that I am doing anything radically different to you.
I tried a number of option. TMR2ON = 1 does not cause and errors but
T2CONbits.TMR2ON is not defined in the header files for these chips.
//Timer 2 on
//TMR2ON = 1;
//T2CONbits.TMR2ON = 1;
T2CON = T2CON | 4;
Bar the one you suggested (not defined) all of the above seem to work. Not
completely sure TMR2 is running - unfortunately gpsim is segfaulting when I
try to view the ram - but that is a different issue that I've yet to try to
fix (and if I can't I need to bring that up elsewhere).

I added in the following at the start of the routine.
//Clear CCP1CON before programming.
CCP1CON = 0;
Unfortunately it did not seem to help.

Thanks,
maybe I'll have to look to see if I have any 18f2xxxx devices and see if I can
get your routine to work.
