GridViewScrollViewer is not available 0912 build, since that build had/has problems, I'm not using it.
I'm unable to find a more recent build and the automatic download flashes on for 2 seconds and I keep missing it. Even you external Update application (which I downloaded and installed) seems to only get build 0912.
But I'm also reading folks are still having problems with the most recent build (whatever that might be).
It would be nice to have a simple "Updates" link/tab/menu item (or whatever) with a list of download links on your web site (always present not hidden away in the depths of your web site) ... but this apparently isn't something deemed important.
But to be clear (I really didn't want to add more code to fix an obvious design problem), the scrollbar should NOT extended into the header, it doesn't scroll the window or the header, it scrolls only the rows so it should NOT extend into the header. So what I'm looking for is a code fix, not a "possible" work-around that would involve me adding A LOT of code all over my application to compensate for what is clearly a design flaw in how the grid scrollbar is being presented.
