Forward and back buttons...not shown
The forward and back buttons, along with other toolbar option buttons are not shown. I can hover over the spaces and see the pop-up but the space is whited-out. It's not only in Safari I've experienced that but in other areas, like Activity Monitor for example. Has this happened to anyone else and can someone please assist?
Thanks
