When viewing any of the lists under the various tabs other than "summary", if there's more than a window full of content, the scroll bar "fights" being scrolled further than about halfway. If I manage to get it to the bottom of the page, it will re-scroll itself up to the top. It's acting as if it is reloading some content below -- and indeed there's a little notification continually popping up in the browser's status bar that something has "Finished loading" -- and constantly resizing the page.
UPDATE: In addition, items with disclosure triangles, such as individual reputation changes or edits, will not display; they open very briefly and immediately re-close.
This was happening with a WebKit browser, OmniWeb 5.11 (v622.15) and Safari 5.0.1 (6533.17.8), on Mac OS X 10.6.8, and continued after I updated to OS X 10.7.3 with Safari v5.1.3. I don't see it with Chrome or Firefox.
