    You're welcome... just make sure that your Zener and resistor are rated to handle it ...
    Resistor 68ohm... (12-5)/68=103mA, 103mA*103mA * 68 = 0.72W => 1 watt
    Zener 5 Volt : 5*103mA = .515 Watt => could be 1/2 watt... i calculate the worst case, VMax,No Load

    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.
