This is the silliest bug in ages! No seriously!

MS, you really SUCK on this one ;)

I got it working, my code was actually correct from the beginning (ie, two days ago ;))

As the article said, you need Disable Script Debugging (Internet Explorer) unchecked.

BUT Disable Script Debugging (Other) must be checked (in Internet Options > Advanced).

Weird huh? I got the tip from here: http://www.delphigroups.info/2/9/938468.html (2005-04-29 09:42:48 PM).

Yes, that's 6 years ago. I'm surprised, no, amazed, that such a thing could be possible and not documented anywhere.

Edit: Programmatic fix:

uses Registry;

// ...

  with TRegistry.Create do
    try
      RootKey:=HKEY_CURRENT_USER;
      if OpenKey('\Software\Microsoft\Internet Explorer\Main',False) then begin
        WriteString('DisableScriptDebuggerIE','no');
        WriteString('Disable Script Debugger','yes');
        CloseKey;
      end;
    finally
      Free;
    end;

// ...
