Visible Face in Wireframe Mode

Hi! I’m using Blender 2.65a (fresh download) in Linux Mint Cinammon 14. I’m having this bit of an annoying problem: when I enter Edit Mode and then view my object in WireFrame Mode there’s always one face that looks white. I’m attaching a screenshot. Is this normal? I hadn’t noticed this in earlier versions and different Linux machines.

Thnx for the help! =]

That’s the Active Face, don’t worry about it, it’s normal.

Thank you very much =] Is there a way to deactivate the Active Face? I’ve never heard about it before, what’s it for?

(srry for the annoying questions… =] )
