This is with JDK1.1.1 on win32 only. It doesn't happen with JDK 1.1 and
it doesn't happen on Solaris.

If you select a menu item, then when you release the mouse the underlying
window gets a bogus mouseClicked event.

I ran into this with the BeanBox where some of the menu items cause you to
start a sequence where you have to click on a target bean or on a target
location in the BeanBox. I discovered I was getting a bogus mouseclick
under where the MenuItem had been. Unfortunately it's relatively difficult to
workaround as there is no obvious way to spot that the mouse click event is
really a bogus side-effect of the menu action.

The following code fragment demos the problem. Select the bargle menuitem
and you will get a gratuitous "clicked" message.
