Any technique which does a CopyBits directly to the screen is not
compatible with MultiFinder.  A better way to do it is to draw the
contents of each window in an offscreen bitmap, then copy that bitmap
into the window.  The frame of the window cannot be displayed into
an offscreen bitmap and copied onscreen if you want to remain compatible
with MultiFinder and other future system software.
