What happened to my post width?

[4x4 Mecca]

Thanks. I do have quite a few hacks installed. That's why I was asking where to start looking. I don't have any "column on X side" type of hacks installed though. I'm off to look in my postbit area.

I searched every edited template, I didn't see one that might cause this, but I could have missed something.

Something else weird. When ever I edit someones post, it then goes to full width when I hit save, but the rest of the posts are narrow still
