You're using a Handler.Box, I assume? How are you getting this to stay
on the map? every implementation I know of, it disappears when you let
go.
In general, controls are stationary: if you want something to stick on
the map, you're going to need to draw it in some other way than as a
control, because it needs to be in the viewport div in order to move
with the map. The best way to do this is probably via a temporary vector
layer, since this will correctly handle things like map zooms, drags,
etc.
