It was when testing with Internet Explorer that I discovered an issue. I am testing with IE versions 6.0 and 8.0.

When the drop is from an external source (that is not another dgrid), the list of nodes isn't guaranteed to be a NodeList. I am dragging from a dijit.Tree to a dgrid. It appears that dijit.tree.dndSource isn't collecting the selection into a NodeList.

So, really, the change I made may only apply to DnD.onDropExternal, as when onDropInternal is called, the nodes are of NodeList, as you say.
