I am having some menu troubles with my script, here is my code (only for the menu):

code:

---

function OnGetScriptMenu (Location)
{
    var ScriptMenu = "<ScriptMenu>";
    ScriptMenu    +=     "<MenuEntry Id=\"MnuAbout\">About...</MenuEntry>";
    ScriptMenu    += "</ScriptMenu>";
   
    return ScriptMenu;
}

function OnEvent_MenuClicked ("MnuAbout", Location, OriginWnd)
{
    MsgPlus.CreateWnd('Window.xml', 'About');
}

---

When activating the script it says i have an error if i remove the:

code:

---

function OnEvent_MenuClicked ("MnuAbout", Location, OriginWnd)
{
    MsgPlus.CreateWnd('Window.xml', 'About');
}

---

It works again and if i just rename the "MnuAbout" to MenuItemId it works again. I just want the about button to work.
