Do you have VB6? Can you create a testprogram? If not then I can send you one.
Just create an empty form and place the SSTab on it (the one from tab control,
not the one in the standard palette). This fails on on my computer and I don't
know how wine could detect if it's a headerless picture or no picture at all
if they look the same (so far).
