Normally, when an action function tells the menu-processing function to move up several levels, the move is not made in one jump. Rather, each level of the menu is retrieved and displayed, until the desired level is reached.
For standard menus, the rapid, sequential display of menus will appear as "flashing" of the menus. The flashing will be especially apparent on slow displays. You can prevent this flashing by turning OFF the form option MNREDISPLAY. You must turn off menu re-display for all menus in the tree. You can either change the default option setting before creating the menu forms, or you can change the setting in each menu form after it is created.
Warning: Turning off menu redisplay is useful only for standard menus, where all sub-menus are identical in size and location to the top-level menu.
