Hi,

I wrote a program that interrupts on TMR0 overflows in the MPLAB simulation,
but for some odd reason it doesn't work when programmed in a circuit.  I
have confirmed that the rest of the program and TMR0 are working, but the
interrupt just doesn't fire when put into an actual circuit.  What could be
the problem?

(TMR0 source is CLKOUT)

Thanks.
