/*
 * an option menu test.
 *
 * this test shows that 0.86.9 won't properly handle option menus that
 * aren't made using XmCreatePulldownMenu.   This is important if you need
 * to use non-default visuals. (e.g. if you want to put your menus in
 * overlay planes on SGIs).  Note that the menu is created and you can pop
 * it up, but you can't select any of the options, nor are they
 * highlighted.
