PART_DragElement
what is the purpose of that? In the sample you have it on a control that is not the content presenter... I thought it representet the actual content being dragged.
@ButchersBoy (taking it back a week or so) "maybe stick a breakpoint in where the window gets created and post (or look at the call-stack)? The nugget package includes source so you might be able to step back and get some more clues..."
I'm not using any custom window factory; I'm just using it like the example, so I'm not sure where I would stick the break point?
