I am running an application that pops up 2 frames and a window. On clicking a menu on one of the frames, a modal dialog is shown. This dialog is set with application modality. On clicking a button on the modal dialog, a file dialog opens up. When all these frames are shown, I am right clicking the java group of windows on the taskbar and clicking 'cascade' option. As soon as I click this, I could see lot of flickering happening on the screen and the system hangs. I could not do anything on the system. Even I am not able to kill the java process.

This is noticed only on WinXP with the following PIT build:
java version "1.6.0-awt.pit-int-jcg-win-03"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.6.0-awt.pit-int-jcg-win-03-java2d_06_may_2005_09_06-b00)
Java HotSpot(TM) Client VM (build 1.6.0-ea-b35, mixed mode)

This is pretty serious since it brings the entire system to halt. I am not able to reproduce this on Mustang-b36.

Run the attached test and you would see 2 frames and a window. Click on the menu in the frame. A dialog will open up. Click on the open button on the dialog. A file dialog would come up. Right click on the java group of windows in the taskbar and click cascade option. That's the end of it.
