        The test window will contain several kinds of menus.

        * A menu bar with two menus labeled "1 - First Menu" and "2 - Second Menu"
        * A drop down combo box - ie a button which pops up a menu when clicked
        * Clicking any where on the background of the window will display a popup menu

        That is 4 menus in total.

        For each case, verify that the menu can be cancelled (hidden) in two ways
        1) Click to display the menu, then to hide it, press the ESCAPE key.
        2) Click to display the menu, then to hide it, LEFT click on the window background.
        Note : the popup menu must be displayed using RIGHT click, the others use LEFT click.

        Notice each time you perform a hide/cancel action an appropriate message should
        appear in the log area
        If this is true for all 8 combinations of menus + hide actions the test PASSES
