Anyone?????

if you enable interrupts and provide no code to service the interrupt and worse still provide no code to reset the interrupt flag what do you expect to happen ?

Here you are:

ISR:
asm
        movwf   wsave           ; Save WREG
        swapf   STATUS, W
        clrf    STATUS          ; Point to bank 0
        movwf   ssave           ; Save STATUS
        movf    FSR,w
        movwf   fsave          ; save FSR
        movf    PCLATH, W       ; Save PCLATH
        movwf   psave


        ; get ready to jump within the ISR page
        movlw   ((INTHAND) >> 8) ; Set PCLATH for jump
        movwf   PCLATH
        btfsc   INTCON, INTF
        goto    ZeroCrossingInt

T0Overflow
        bcf     INTCON, T0IF    ; clear the timer overflow flag

        goto    EndInt

ZeroCrossingInt
        bcf     INTCON, INTF    ; clear the interrupt

EndInt  ; restore the machine state and return from interrupts
        movf    fsave,w
        movwf   FSR             ; restore FSR
        movf    psave,w
        movwf   PCLATH          ; restore PCH
        swapf   ssave,w
        movwf   STATUS          ; restore Status
        swapf   wsave,f
        swapf   wsave,w         ; restore WREG
        retfie
endasm
