Hovering over tabs when working on a differnt app/window
I use to be able to work on one app/window and hover over multiple tabs to obtain brief details on the browser (tabs) as it sits behind the app/window I'm currently working on. Since about a week ago, this feature has gone away. Now I have to be on the browser to be able to hover over the tabs to obtain the info I need on the tabs. I do this to compare the order # that displays on the tabs for what I use it for. How do I get this feature back. I want to be able to hover over tabs to view the small details even when not currently on the browser itself. Please help.
