+Summary: ListBox does not update the entire list on scrolling by keys
+
+When you scroll listbox up or down by keyboard navigation by up, down,
+pageup, pagedown, home or end, it does not redraw the required items area.
+
+Steps to reproduce the problem:
+1. Run winforms/listbox/swf-listbox-selections.exe
+2. press any of the keys mentioned above.
+
+Actual Results:
+
+It updates only selected item and leaves remaining items as is. Thus, say
+we have list items with selected item like 
+
+----------------
+ this is item 0
+ this is item 1
+[this is item 2]
+ this is item 3
+----------------
+
+after hitting down key two times, it becomes
+
+----------------
+ this is item 0
+ this is item 1
+ this is item 3
+[this is item 4]
+----------------
+
+Expected Results:
+
+It should be
+
+----------------
+ this is item 1
+ this is item 2
+ this is item 3
+[this is item 4]
+----------------
+
+Additional Information:
+
+Might be only true to windows (haven't tried on Linux).
