hmmm, it is perhaps not expected by the user. Currently  the mouse
drags the box and rendered data precisely if you don't resize
the display. But if you reduce the size of the frame, the box and
data lag behind; and if you increase the size of the frame much
larger than the original size (easy to happen when your initial
frame is small), the box and and data could shoot across the
screen if you just move the mouse a little.

I updated the driver and the result is the same. I have
tracked it down to something related to my graphic card
(Matrox Millennium II + DirectX). I will get back to this when
I find a solution. Thanks for the pointer.
