Issue with loading tabs in TLN

Hi,

I am facing an issue with my sap portal TLN.

If I click on one tab and then navigate to tab 2, the first is still highlighted (though the content loads for second but Top and second level nav still shows tab1 text/details). Then if I click on tab 2 again, its finally highlighted

Below screenshot is when I do one click for navigating from system admin to content admin:

On second click, it will finally highlight content admin with its second level navigation tabs.

Thanks,

Somya
