tab click event does not fire some times

[sraojalla]

I am facing a problem where, I have 7 tabs in a tab set. Normally when a tab in a tab set is clicked, it should fire the tabSelected event and shift the focus to the newly selected tab, but occasionally and randomly it so happens that the tabSelected is not getting fired but the focus shifts to the newly selected tab AND it's pane is not getting loaded, so the user is under the impression that the tab has changed, but it is not.

Has anybody seen this behavior with the tabset ?

Enable the EventHandler log category in the Developer Console to troubleshoot. Most likely you have something occluding the tab.
