The problem is the following:

The main window has only a VERTICAL scrollbar.

When asked to scroll vertically (eg in WM_VSCROLL handler), the program request
the scroll range of the HORIZONTAL scrollbar. Wine returns min,max == 0,0 and
the programs does not scroll.

A test on windows XP shows that if there is no HORIZONTAL AND no VERTICAL
scrollbar then this is correct. However if a VERTICAL scrollbar is present, the
horizontal scrollbar range is set to 0,100.

I must study the stuff better to seen how to fix this properly.
