If your migrated app uses VB3-style drag-and-drop, in some rare cases this feature might not work properly if you have concluded a previous drag-and-drop operation in an “irregular” way.
In such cases, VB Migration Partner’s support library fails to realize that the drag-and-drop operation is concluded and prevents you from attempting a new one.
For this reason, VB Migration Partner version 1.33 and later versions supports the special VB6Utils.StopDragDrop method, which you can use to manually signal that a drag-and-drop operation has concluded. If necessary, you typically do this on entry to the DragDrop event handler:
Private Sub Picture2_DragDrop(Source As Control, X As Single, Y As Single)
