Try to init change (MUIM_Group_InitChange) a group where have list and remove
this list and add it again or exit change a group (MUIM_Group_ExitChange).
However it might resize the window!

MUIA_... is object attribute not method! When you'll use set( list,
MUIA_List_Active, entry ); everything should be fine.
BTW, please considier using NList/NListview instead of List/Listview. There're
more powerful and looks better. You don't have to even change all
attributes/methods because NList.mcc is emulating standard List.mui class.
