I can't get TMR0 overflow interrupt to work at all.

I use it to increment a counter (PWMCOUNTER) which is compared with a
certain value (PWM), if PWMCOUNTER<PWM a bit in PORTB is set, otherwise it
is reset. (using 1/8 prescaler on RTCC, INTCON: GIE and T0IE are 1, all
others 0)

I can't get it to work: the output is always LOW, which means the interrupt
doesn't happen. It works in MPSIM.

does anybody have a working fragment of such a thing. (anything with a TMR0
overflow interrupt would be great)

thank you,
