Comment (by haakeyar):

 Replying to [comment:5 haakeyar]:
 > A concern with both patches is that in the call to this.map.setCenter in
 panMap, the third argument is this.handler.dragging. The value of that
 could potentionally become false before the timeout is run. I have no idea
 what that argument does and why it is there in the first place (wouldn't
 it always be true?), but it will have to bee looked into. (If no one else
 does, I'll probably look into it on saturday.)
 From the documentation on the third argument to setCenter:
 "dragging       {Boolean} Specifies whether or not to trigger
 movestart/end events"
 http://dev.openlayers.org/apidocs/files/OpenLayers/Map-
 js.html#OpenLayers.Map.setCenter

 So, I would guess that we could just set the third argument to true, since
 that's what it would have been if the action wasn't delayed (as far as I
 can see), but I might be wrong. I'll have to leave that to you hardcore
 OpenLayers developers.
