Since 23.1, Emacs on w32 allows the scroll thumb to shrink while being 
dragged at the bottom of the buffer.  Previous versions fixed the size 
of the thumb while dragging, which I think is the brain damage which GTK 
forces on you that Miles is refering to, as you are unable to reach the 
bottom of the buffer by dragging the scrollbar in some circumstances 
because of assumptions Emacs makes to relate characters to pages of 
scrolling without wasting time doing a full calculation over the buffer.
