Here is a problem I am having with regions:

I create a region and set it equal to a rectangle with a call to RectRgn.
I then check to see if the mouse is clicked within the region and
if it is, I call DragGrayRgn with a  nil for the actionProc. After
dragging the region across the window, I release the mouse button. If I
try to drag the region again, however, I find that the region is
defined as the frame, not the enclosed area of the rectangle.  

What gives?!! I have to grab it by its border (PtInRgn is true for only
this condition).  Obviously I want the region to remain unchanged.

Hoping for an answer......
