Screen Copy onto Window???

Hello all,

I have a problem that I could'nt find an answer for on
the listserve (prior post), so here goes.

I have a bitmap that has rounded corners and am setting
transparent the outter edges of the bitmap (easy enough)

The problem I have is when I create a Window for this
bitmap to fit ontop of, I want to capture the SCREEN
in the area of my new Window before I paint it
and set the captured Screen ontop of the new Window
before I display my bitmap...
(much like McAfee does in all their newest ware's)
essentially hideing the Window with a portion of the screen
before I drew the Window. If that makes it easier for some.

Here is an attempt (but failure) to do this.

constant
ScreenBuffer = create( Pixmap, "", 0, 50, 50, 500, 400, 0 )

procedure CopyScreenToBuffer()
  --myBitmap will start at x = 50 y = 50
  copyBlt( ScreenBuffer, 50, 50, Screen )
end procedure
CopyScreenToBuffer()

constant

procedure CopyBufferToScreen()
  copyBlt( Screen, 50, 50, ScreenBuffer )
  repaintWindow ( Win )
end procedure
onPaint[Win] = routine_id("CopyBufferToScreen")

What am I doing wrong???

Is there a better, smoother, faster way?
preferably one that works. hehe
