Hi, i find a bug in the java.awt.List, when i remove an item from the
list, the List doesn't refresh apropiatelly, and the item persist
appearing, in windows this doesn't have that behavior.
p.d. i send you the main application that show a frame with the list and
tries to remove an item selected from the list.
