Hi, and sorry if this answer comes late. Yes, by default the drag
handler's mousedown method returns false. You can change that by
setting stopDown to false in the drag handler instance. If you want to
have that in every drag handler, even those that you don't create
yourself, you can do:

OpenLayers.Handler.Drag.prototype.stopDown = false;

soon enough if you application code.

Cheers,
