I have two suggestions featuring the Confirm exit feature.
[*]Beep on confirm exit.

    Right, you are probably wondering what I mean on beep on confirm exit, I will show you.
    Code:
    <Script language="JavaScript">
function ConfirmExit() {
  alert("Are you sure you want to exit mIRC? \nChannel Windows are open.");
}
</Script>

<Form>
<Input tYPE="Button" Value="Confirm Exit" OnClick="ConfirmExit()">
</Form>

    Now, I expect most of you know that sound, if you notice it has the exclamation mark on the alert box from the mIRC 6.1 Confirm Exit. My question is: could you add that sound to the Confirm Exit please?
    [*]Disable the close button [X] in Confirm Exit

      Since you can only answer Yes or No to the "Are you sure you want to exit mIRC? Channel Windows are open." Why is the [X] enabled and allowed to be clicked, it doesn't really need to be enabled because, it'd be pointless clicking the [X] when mIRC users could just click "No".
      I am not meaning to sound ungrateful, but it is just a suggestion nonethe less.
