Comment 2 for bug 876734

This bug also affects Ubuntu 12.04 beta 2.
With all the other window controls on the left by default, the left-scrollbar should not be that unusual a choice. Since finding the left scrollbar is so difficult (scroll length is set to 2048, so the invisible red indicator is pretty small), a workaround is to simply suppress the new scroll bar, and fall back to the old one. which is always visible.
