         2 areas yellow and red should be seen.

          Clicking in these areas should cause a menu to popup. See if you can
          get the menu to stay up and grab all input. One way to do this is to
          click and hold the mouse to popup the menu, move away/outside of the
          menu and release the mouse. At that point, the input is grabbed and
          the *only* way out is to hit the escape key. Try this on both areas.

          To make things worse, when the popup menu is up, click repeatedly on
          the LightWeight component area. Hit escape. Do you see multiple menus appearing ?

          If you do not see either of the two problems above, the problem is fixed.
