it is possible that you are handling the OnMouseClick event some where 
else and playing around with the cursor when you shouldn't be?

Hi Jamie,
Thanks for your response. Iam using drag & drop as a feature within a grid 
component.  This component only offers OnMouseDown,Up,Move events and does 
not give access to OnMouseClick.  I am using BeginDrag within the 
OnMouseDown event.

I think you are possibly correct in that the grid is capturing the 
MouseClick event before I get access through the MouseDown event.  I dont 
know how to interupt that access and gain control over the mouse events.

Thanks again for your help.
Mike

  if your working with a third party control it's very possible that
the cursor maybe getting reset! it that is the case then it was
poorly written. possibly code in the mouse move event to force the
cursor to remain at a constant.
  maybe you should perform your own test in the OnMouse move to detect
the current Mouse being used in the drag..
