My application needs IE browser to FF browser or MS Word application communication. For example, if I click a button at one browser (For example IE) and move the mouse focus to other browser (For example FireFox/Chrome) or application window (For example, Notepad/MS Word). Then, button click event should display a message.

I can do Browser to Browser communication as similar to child browser window to parent browser window communication using window.opener function. But, I don't know how to make the communication from child browser window to any focused browser/application window.

Please help me in this.
