Open in New TAB -- IE 7, IE8, IE9 beta

My XP machines are still on IE7 but WIN 7 has IE8 and my testbed WIN 7 Enterprise 64 now has IE9 beta, just because it's there ....

 

But on IE 8 and IE 9 I have the same thing with Tabbed browsing that differs from IE 7 whether on XP or WIN 7 32 -- when I tell it to open a link on a New Tab it does so but the focus stays on the old tab whereas in IE 7 it flips to the new tab without my having to click on the tab.

 

I'm sure there is a setting somewhere but can someone remind me where it is? I've been through Advanced Settings and I don't spot it there nor does there seem to be anything by right mouse clicking on the bar the tabs come up in ...

 

TIA
