[IDEA] Make the little scrollbars visible

[Tim Curtis]

Other than the z-index issue I experienced with Safari, Chrome works fine on my end. I'll prolly remove the z-indez property if Chrome is not affected. Also it might be worth taking a look at that pointer CSS again.

IME, "hidden until hover" scrollbars i.e overlay scrollbars have been problematic in all Browsers and IMO a big mess.
