    I've been looking over your code for about 10 minutes and nothing is jumping out at me. My only thought is something flaky is going on during the power down stage where PORTB.4 goes high momentarily. You could try adding a debounce or a small pause at the beginning of the SWITCH routine and see if there is any change.

    Just tried that, didn't seem to make much difference...It toggled a bit smoother though.

    My guess is somehow the program is causing the EEPROM value to switch at startup or shutdown. No clue how though.

    Thank you,

    Have you tried switching this;
    Code:
    SWITCH:
    IF setting=1 THEN 'if setting is 1, write 2 to EEPROM
    WRITE 1,%00000010
    ENDIF
    IF setting=2 THEN 'if setting is 2, write 1 to EEPROM
    WRITE 1,%00000001
    ENDIF
    To this;
    Code:
    SWITCH:
    IF setting=1 THEN 'if setting is 1, write 1 to EEPROM
    WRITE 1,%00000001
    ENDIF
    IF setting=2 THEN 'if setting is 2, write 2 to EEPROM
    WRITE 1,%00000010
    ENDIF
    Regards,
