Has anyone actually gotten phpDesigner debugging CI?

I come from the Visual Studio world where I feel like I've been spoiled since things like debugging just work. I have yet to figure out how to get the phpDesigner debugger to work with CI. I want to be able to step through code. Is this even possible? If so, what are the steps? Right now I'm just echoing out stuff to the page and using FireBug but I would really like some more robust options (like the aforementioned stepping through code).
