Hello everybody,
I have made lots of search inside studioskin but i haven't resolved my problems.
Windows 8.1
When i dont check : "Do not user per pixel frames even if the skin supplies them", i have this problem with all my skins :

How may i fix this ? Is it a WindowBlind's bug ?
I dont want transparency and how to change the white color ?
In Firefox, how to fix this ?

And for finish ...

Thx you very much !
