Worked on bug #3994: Scroll position is wrong after switching views. This bug has been a thorn in my side for a very long time, and sconsumed several days of my time. It turned out to be a windows specific wx bug caused by a delayed sizer problem -- and I think delayed sizer problems are the source of a few other bugs. Anyway Robin finally came up with a simple workaround so it's no longer on my plate and I've reassigned it to davids.
