Chris,

	The -s overrides the LCD locking that is done.  Basically, when the lcd is
displaying menus, it creates a lock file that other calls to lcd-write and
lcd-swrite should honor and return failure codes when a menu is being
displayed.  When writing scripts in the /etc/lcd.d structure to create new
panel menus, you should use the -s option.  All other times you should not
use the -s or you may end up expecting menu input but displaying something
totally different.
