Side note:

I would caution against using this type of paradigm (two layers of tabs in your application).  We did it and the user experience feedback wasn't very good.  Our UI designers also weren't big on having tabs in the menu and tabs in the content area.  While this was specific to our application implementation, if you look at Word and IExplore, each has one or the other, not both.  But you never know, maybe next gen UI will have the combo!

Off my soapbox.
