Use wind_update(BEG_UPDATE) and wind_update(END_UPDATE) to prevent
the AES screen manager from taking care of menus and the like while
you are doing your dialog tricks on the screen. This hint is valid
for any situation where you are doing something on the screen (VDI
calls, but objc_change() calls also).
