Menu scrolling

[alexander_liberson]

     Hello,
     
     We are using ncurses 5.1 libraries on AIX 4.3.3 with IBM's CSet 3.6.6 
     compiler.
     
     Our menu has more items that can fit on one page, so we use 
     set_format(FRAME_ROWS,1) to limit the number of items displayed on the 
     page. When we run our application from a telnet session on a WinNT PC 
     emulating the ibm3151 terminal, the menu scrolls fine. When we run the 
     application from a vt220 hand-held scanner, the very last item scrolls 
     up one row, but the items above it stay in the same positions (not 
     moving up).  
     
     We have a class that inherits from NCursesMenu. Here is its 
     constructor:
     
     NWMenu::NWMenu(char* menuname) : NCursesMenu (14,
                                                   70,
                                                   2, 0),
                                                   menuName(menuname)
     {
        initAndDisplay();
     }
     
     
     Thank You,
