Sorry to hear that, it works for me and I don't need it.
Here's my configuration at the time when it was working:
XP
PowerToys set to scroll 3 lines
MouseWare 9.73 set to 3 lines, NO Office Compatibility
The configuration I normally use (doesn't allow scroll in local window):
XP
MouseWare set to NO SCROLL
PowerToys set to 3 lines
(order matters)
