FULL PRODUCT VERSION :
ava version " 1.7.0_09 "
Java(TM) SE Runtime Environment (build 1.7.0_09-b05)

ADDITIONAL OS VERSION INFORMATION :
Mac OSX Mountain Lion 10.8.2

A DESCRIPTION OF THE PROBLEM :
We have a screen sharing applet that opens up a Swing JFrame and uses the Robot class to capture the screen behind the empty frame.

The user should be able to click through the frame and interact with whatever lies behind the applet. This works fine on Windows and used to work with Apple's Java version, but with Java 7 for Mac it does not work. Mouse clicks does not go through the JFrame.

The JFrame uses:

setAlwaysOnTop(true);
setUndecorated(true);

Tried using:

AWTUtilities.setWindowOpaque(false);

Or

setBackground(new Color(0, 0, 0, 0));

With Apple's version calling:

getRootPane().putClientProperty( " apple.awt.draggableWindowBackground " , Boolean.FALSE);

did the trick, but this is no longer working.

Please advise.

Thanks, Eilon
