Selected tab in a Tab Page set?

This question is worth 250 points and they will be awarded to the provider of an answer that will help me solve my problem with Tabs.

Hi, I have a Tab Page set with several tabs. When the User clicks on any tab, obviously he/she will see the selected page corresponding to that tab.  However,  I would like to make the actual tab itself stand out more visibly.  In other words, I'd like to either change the color of the tab itself, or even part of it, like Windows XP does with the little orange bar above the text. Or maybe bold the text inside the tab, or change the text’s color, but nothing I do seems to work.  Does anyone know how to make a selected tab stand out more visibly than the others that are not selected?  Any visible change from the other tabs would work, but I wouldn’t want to have to create a custom tab object, as I don’t know exactly how to do that, or if it can even be done.  Currently, I have a label over each tab with the same text in bold font. When the tab is selected, the label becomes visible. When the tab is not selected, the label becomes disabled. I'd like a better way, as this is too combersome when you have many tabs.

Thanks for your help...!
