/* to use this cascading menu software, need to declare 
menuDelayMS and set to the number of milliseconds before the menu is to appear - 100 seems normal - actually value is set in Bar item definition
menuHoldMS and to the number of milliseconds before the menu should disappear if cursor not over menu - 1500 seems normal
nShowMenuStart unless ShowMenuStart is an attribute of the top menu bar, set to 0 for menus below and 1 for menus off to side
Assumes there are up to 3 menubars, menuBarTop, menuBarSide and menuBarReport, or one menuBar
