onDrag blocks cell edit

I have a grid with some editable cells and I’m attempting to add some drag-n-drop functionality as well. As soon as I add:

grid.enableDragAndDrop(true); grid.attachEvent("onDrag",function(sId,tId,sObj,tObj,sInd,tInd){ return false; });
I have an issue. When double-clicking the cells for edit, they change to a text box, but it wont allow input. This seems to be following the onDrag event as I can take just the event handler out and it works fine. I was intending to add some custom code to the event, but found this first.

Any tips??
