--- Comment #7 from Dylan Smith dylan.ah.smith@gmail.com 2008-10-04 00:58:20 --- I found the there is an underlying problem with GetScrollBarInfo returning the scrollbar bounds in client co-ordinates rather than screen coordinates. This should be fixed first, since it would invalidate my richedit fix.
