I’n using a CExtScrollBar to scroll an image.  I expect to get messages such as SB_LINEUP, SB_LINEDOWN, etc.  But all I get is SB_THUMBTRACK.  I have user preferences on how much a line or a page should scroll.  It’s not a linear scale so I can’t do what I want by setting the scrollbar range.

There’s is similar dicsucssion about this in the thread titled "bug inside CExtScrollBar" Aug 5, 2008.

I’m on 2.83

This is fixed on the later Prof-UIS versions. You can get the source code of the CExtScrollBar class from the new Prof-UIS version or switch to just released Prof-UIS 2.87.
