Tabbed tracking window ?
 

I'm hoping someone might be able to help me with an issue I'm having with this window.
I'm trying to make a tracking window with two tabs, one that shows the Bard/Druid and other that shows the Ranger options.
But, for some reason, everything seems to work fine on the bard/druid tab but nothing works on the ranger tab.
Nothing is shown in the track list and even the buttons don't work.

No idea why, if anyone has any help/suggestions I'd appreciate it.

Thanks.
