how to change the z order of browser window

how to change the z order of browser window

I am opening a new window to allow an 2 second recording to play.  Once the window is open and audio is playing  I use the setTimeout() to close the window.  This is working, but when the new window is open it is in the middle of the screen. If i click the main window then the new window is forced behind the main window. 

Is there a way to use jquery and force the new window into the background? or is there a mechanism that would me a way to force a click on the main window??
