Well, I have a problem. I'm currently using the interface in Longhorn 5048, however, he has an annoying flaw: almost every time I use the drag and drop in explorer, or the source window hangs when I try to close it (so is the frame without nothing inside) or the target window is the same.
I urge those who know how I can fix this, I believe that the problem lies in Explorer it, and who know of a way, please talk to. thank you

Leave that alone. Longhorn 5048's explorer is known for being that unstable & buggy.
