JMenu dismissal action in WindowsLookAndFeel changed for 1.4.1_02 ?

Question

Hi all,
It seems to me that the way menus are 'dismissed' in WindowsLookAndFeel has changed in the 1.4.1_02 release. The example program included in this post, when run on 1.3.1_06 (in WindowsLookAndFeel mode) keeps the menu visible until the selected action completes (same as for metal/default L & F modes). However, when run on a 1.4.1_02 system, while the default and metal L & F actions are unchanged, when using WindowsLookAndFeel the menu disappears immediately after the menu item is selected, and leaves an 'empty' rectangle behind! Seems to me that this action change is a bug, but I am hoping that someone might be able to explain what is going on. I could perhaps live with this if the background under the dismissed menu was repainted as part of the dismissal action - but I am unable to make this happen! Again, any insight from others would be most welcome! I am sure this worked with 1.4.1_01, but cannot test this at present.

------ start test code ------
* Test menu dismissal interval on different JDK versions.
*'WindowsLookAndFeel' appears to act very differently on 1.4.1_02
* compared to earlier versions.
* Menus seem to be dismissed immediately. Only an issue
* with 'WindowsLookAndFeel' ??

I have since determined that the problem is in FileSystemView.getSystemIcon, which returns a garbage icon on my system.
