In 3.6.0, the settings page has some broken layout (at least for me). The active panel shows to the right of the tabs.
The following changes in Firebug fixed it for me:
- .ui-tabs-nav a span - padding-top from 6px to 0
- #hasadmintabs ul.ui-tabs-nav - height from 29px to 32px (or 38px when not altering the span padding-top)
