Alert Box in IE Tester

IE Tester has no console, and alert boxes seem to be ignored in this software. Is this expected behavior? If so, how does one go about debugging javascript using this tool?

I have debug bar installed, but it doesn't seem to do anything useful besides allowing me to look that the DOM.

I need to be able to check 开发者_如何学编程the state of various objects during script execution, but I don't know how to do this without a console or alert boxes. Any help is greatly appreciated.
