Modal Dialog Windows in Selenium

Hi,

Can we handle modal dialog windows/pop up using Selenium?
I have a task where I need to open a modal dialog using selenium code and then perform some actions on the web elements(button) appearing on this modal dialog box. Example: Open a new modal dialog window from already open modal dialog window.

I read many posts on google and came to know that selenium do not support modal dialogs because selenium run on Java script and it looses it's window handle when we open modal dialog popup.

There is no control on window handle when modal dialog pop up opens and hance system hangs.

In short, selenium do not support Modal Dialog Pop Ups and cant automate the actions on modal dialog windows.

Please suggest if someone knows any alternates?

Note: Here I mean modal dialog windows and not normal windows

Thanks,
Lovekesh
