Hmmm...

I have been doing some tests at home that suggest that native richedit 
never reads the actual scrollbar state (with either GetScrollInfo or 
GetScrollBarInfo), but caches it instead, and that when the text does 
not need to be scrolled, the native behavior is to hide the scrollbar, 
not set it to zero (so the previous scroll range of the hidden scrollbar 
is still externally readable). The values on win9x seem bogus, so it 
seems that either native leaves the scrollbars uninitialized until first 
use, or GetScrollInfo is failing on the richedit window. I will look 
into it.
