Opaque Tab Question

Greetings All!

I've removed the curtains from my Today screen et al, but the selected tab is still black and opaque. Is there any way to make the selected tab transparent or at least somewhat so?

I've searched around the forums and I've found a reference to a custom hh_fw_selectedfill.png file that was labled "transparent selected". However, I don't see a file named that anywhere in my phone so that I can overlay it.

Any thoughts or suggestions?

Many thanks

Cheers, Henri
