Fix: Listbox was sometimes sending EGET_LISTBOX_SELECTED_AGAIN instead of EGET_LISTBOX_CHANGED.

Browse Source 
When pressed mouse was moved over an item before releasing the mouse button it was sending immediately EGET_LISTBOX_SELECTED_AGAIN instead of expected EGET_LISTBOX_CHANGED (mouse  move changes do not send any events).
