The OI_abbr_menu probably has an underlying menu type of OI_button_menu.
OI_button_menu objects have cells which are selected only during the
period while they are actually firing.  The abbr_menu shows the current
default cell, but the cell is not selected; it is simply the only one
visible.  Try asking for the default cell and see what you get.  Or
change the underlying menu type to some form of OI_excl_*_menu.
