--- Comment #27 from Anastasius Focht <focht at gmx.net> ---
Hello folks,

confirming - there are multiple issues here.

The most obvious one is a jscript parser failure:

Wine's jscript parser doesn't recognize 'objectid::eventname' style function
declarations.

That's Microsoft IE specific ECMAScript 'extension' which allows to wire up
event callbacks for ActiveX objects.

--- snip ---
function window::onload()
{
    SetText(EulaNote);
    SetText(EulaLink);
    SetText(Note1);
    SetText(Note2);
    SetText(Copyright);

    SetButton(PlayButton);
    SetButton(AdvancedButton);
    SetButton(InstallDedicatedServerButton);
    SetButton(InstallMapEditorButton);

    //PlayButton.src = PlayButton.hover;

    SetTabStop(PlayButton, 1, OnPlay);
    SetTabStop(AdvancedButton, 2, OnAdvanced);
    SetTabStop(InstallDedicatedServerButton, 3, OnInstallDedicatedServer);
    SetTabStop(InstallMapEditorButton, 4, OnInstallMapEditor);
    SetTabStop(EulaLink, 5);

    animationTimerId = window.setInterval("OnAnimateTracks();",
animationInterval);
    //window.setTimeout("OnChangeBackground()",
initialChangeBackgroundInterval);
    main.filters[0].Apply();
    content.style.visibility = "visible";
    HelpBox.style.visibility = "visible";
    HelpText.innerText = GetString("DefaultHelp");
    main.filters[0].Play();
}
