If you have a folder sorted by a certain column, and then you click and drag the vertical scrollbar, Explorer will display a little helper rectangle showing where in the sort list you currently are. This is what I'm talking about:
I was wondering if anyone knew how to obtain a handle or UIAutomation ID of that little rectangle (if one exists). So far I've been trying with Spy++ and Inspect, but I can't seem to figure it out (in part because the rectangle is fleeting and disappears as soon as you lift the mouse button). Thank you for any response or guidance.
