[Wine] Wine and Dual core CPU

[dabbill]

I have searched the forums and cant seem to find an answer. I have noticed that when i run games and programs under wine its only useing 1 core. While when i run native Linux apps they use both cores. Also the games and programs that i am running under wine use both cores when run under windows. Is this a bug, or maybe just something i dont have setup correcly on my computer.

Computer specs.
4600+ AMD dual core.
2gig RAM
160gig sata II HD
Geforce 8800GT video card.
Ubuntu 8.04
