drag n drop

[Mr. C Lamont Gilbert]

I have implemented drag n drop for a few years now. But today I discovered that I can not decline a drag-move but accept a drag-copy. The icon is appropriately displayed as the no icon when the action is drag-move, but when the user lets go, its still dropped as a drag-copy.
How is the drag action automatically becoming a drag-copy when the icon is not updating and I never issued a drag-copy, and the original source sees only drag-move as well???
I hope I was clear.
