Popup Window - Lock main screen behind it

Hello,

 I am hoping to find a way to `lock` the main screen behind a Floating pop-up.  I am currently using the window's Layer property = 1 on the pop-up to ensure that it stays on top of the main window even if you click outside of the popup.
 However, you can still interact with the main window behind.  I am looking for a way to completely lock (but not close) the main window behind the popup other than manually 'disabling' all of the objects on the main window.

Thanks.
