Occasionally, clicking "File Status" in the sidebar does not change the view from the history to the commit view. However, clicking the "commit" toolbar icon seems to always work. Also, clicking "History" sometimes does not change the view either. In both these cases, the item is highlighted, but the view does not change. Sometimes, if the view is changed in alternate ways, the sidebar items will start working again. I've noticed it more often with the "File status" item than with "History". I have not determined a specific way to get this state to happen. I believe I first noticed this bug about 3-5 months ago.
