i am having trouble creating a pixmap, or maybe not creating it, but
BitBlt-ing it to a window. if i create the pixmap and then BitBlt it to my
window, it displays static like that of a TV screen on the wrong channel. im
not sure what is wrong, here is my code:

----------------------------------------------------------------------------
-----------------
-- begin code
include win32lib.ew
without warning

atom hLabel, hBackup

hLabel = create( Window, "", NULL, Default, Default, 320, 240, 0 )
hBackup = create( Pixmap, "", NULL, 0, 0, 320, 240, 0 )

procedure onPaint_hLabel( atom x1, atom y1, atom x2, atom y2 )
    bitBlt( hLabel, 0, 0, hBackup, 0, 0, 320, 240, SrcCopy )
end procedure
onPaint[ hLabel ] = routine_id( "onPaint_hLabel" )

WinMain( hLabel, Normal )
-- end code
