I would like to let the user to select a particular area in a graph screenTry using WinSetDrawMode( winInvert ) and WinPaintRectangleFrame(); for an easier life. You *may* need to set the color to black or white before drawing. The advantage is that, being XOR based, you only have to draw the rectangle again to remove it from the screen. This means that you should be able to have your selection rectangle and not have to save the current state of the window.
(The graph screen is now exists). Now I have made a feature that enables the
user to "drag" a dotted rectangle using WinDrawGrayRectangleFrame(),
like the one in windows for selecting icons.
As we couldn't see the initialisation of wholeScreenRect it's hard to say about what might be causing your problems.
