Can you send this message to the mono-devel-list?  Mine hasn't been

Hello,

We found an issue while testing a form that uses
System.Windows.Forms.ListView.

If the last item in a ListView has focus and it is removed by
an another action on the form (i.e. push a button to remove the
current item), then the focused_item_index is not updated when
the VirtualListSize changes, even though that item doesn't exist
anymore. When the ListView receives focus again, it tries to
invalidate the current focused item which causes an
ArgumentOutOfRangeException.

When the VirtualListSize changes, the focus_item_index should
be reset (similar to how it currently resets the selected indices).

Thanks,

Chris Hubbard
