I know it's been a while, but.... This ^^ describes the problem exactly. The top menu bar appears to be a hard-coded, fixed width. If you notice in the first screenshot, I can scroll to the right (look at horizontal scrollbar). In the second shot, I've scrolled as far right as I can go and notice the text (my username, for example) in the top bar. It hasn't moved. The only solution is to make the browser wider.Just shrink your browser window smaller than the width of the top title/control bar - the horizontal scrollbars only scroll the content below it, not the actual bar.
Hmmm, why do I not have any "Attach" options ?
