The problem: When trying to view large documents in CScrollView, the scrollbar's range isn't enough.
The formula: to find the range i use numberoflines * pixelheightofchar.
This doesn't seem to do it when using SetScrollSizes in OnInitialUpdate. It DOES work using SCROLLINFO and SetScrollInfo, but then I lose thumbtracking (without more work to code it in). What gives with SetScrollSizes? Is there some limitation that isn't in the documentation?
