Draw Widget with Pan tool

Hi,
I`m using drawWidget (flexviewer 2.1), I added some mouse events to the graphics made by the tool, but its seems to ignore the pan tool when i`m trying to move inside a graphic. The pan tool only works if I remove all the mouse event listeners from the graphic. I saw the latest version of this widget and it doesn`t have this issue, is there some way to change just this aspect?
