Screen Capture showing blank "Split Buttons" on XP SP3

I have just tested with the manifest removed and when SIV tries to use
BS_SPLITBUTTON the DialogBoxIndirectParam() still fails on Wine.  I also then
tried the same on a real XP SP3 system and there the dialog came up, but the
buttons failed to be drawn. The button windows are actually present when I
checked with Spy++.
