I'm hoping someone can tell me why 'PreFilterMessage' on a registered IMessageFilter is not being called during a drag-drop operation? I need to track mouse coordinates during the drag-drop operation, and I know I can do this with DragOver, but I would
like to have a 'global' view of the mouse position, and DragOver needs to be subscribed to on the individual Controls in my GUI.
Is there an alternative way of tracking the Cursor position during a drag-drop operation, or is there any way I can get my IMessageFilter to receive messages during this?
