In checking out the GLUT demos using "freeglut" I find that the "newave" demo has some menu troubles.  If you bring up the menu outside the reflective area and drag the mouse down through the menu options, the submenus that come up do not disappear properly.  If you select "stop" the menu does not disappear.  I'm running Windows at the moment.
