How to work with EXTJS popup windows

[ssiwani 0]

I have a situation where I have to work with a extjs popup. I did some research and came across the IEAttach function. I tried to use that, however, I was still unable to recognize the window to get a handle on the window.

Anyone has suggestions, examples on how I can work with this window (e.g. to click a button on the window, insert text in the text field etc.)
