Dragging + RowOverHandler

Hi

When I start dragging (LMB down) I stop receiving RowOverHandler events. RowOverHandler appears to be fired only when drag is not started.

The thing I’m trying to do is to drag a button over a row in ListGrid. As I move the mouse (while still dragging) I want to know which row is currently under the mouse pointer.

Do you have any idea on how to enable it?
