black on top windows. i want windows 7 basic scheme color on all windows. Rated 5 out of 5 stars

Hi everybody,
i'm italian user, sorry for my bad english.

Fxopera at the moment it's look likes new opera 16 interface. I want a opera 12 theme for firefox. So i have download old version of this theme, specifically the 21 version.
I ve modified the install.rtf file. in max version i set 25.0. Theme install corrctly, but:

the windows, on top, remains black. I think it's the aero setting. My question is: which file should I modify to make sure that the entire window has the color scheme of windows 7? Specifically i use windows 7 basic theme so i would that firefox is integrated with windows 7 basic theme.

Thank you guys!
