Yahoo Domain Forwarding Problem

I've bought a yahoo domain, and I'm trying to forward it to one blog I have, the problem is, when I go to the domain control panel and I choose the masked forwading option, the domain will forward properly, but I will have a little big problem.

My page title (the one that appears at the top of the browser window), when I load my blog name, everything is proper (Welcome to my Blog)

But when I load it from my forwarded domain everything that appears at the top of the browser window is (mydomain.com), what I want is for the title to be the one I have when loading my blog.

I have tried everything, yahoo control panel doesn't seem to have an option to edit my title.

Can anyone point me to a solution?

Thanks
