--- Comment #4 from Hans Leidekker hans@it.vu.nl 2007-12-17 13:39:46 --- Looks like some handmade rotated text rendering. Notice that the vertical text in the small summary window, which is rotated in the normal way by asking for a font with lfEscapement == 900 is rendered correctly.
In contrast the vertical cells are created by rendering *horizontal* text into a separate bitmap and then blitting the bits back into the original dc. Somewhere in that process things go wrong, given that disabling the BitBlt calls makes the black squares disappear.
