Well, I've been working on a new blog the last few days (thats why I haven't been around lately), I designed it for firefox (it should work in all browsers because firefox is standard compliant).

But now, the layout uses lots of <div>'s and css, it works like a charm in Firefox but when you try to select something in IE, the whole site is selected .

Does anyone know how to fix this?
I've found out that the bug is in the IE stylesheet on the 12th line.

code:

---

.center{
    position:absolute;
    left:50%;
    margin-left: -215px;
    width: 430px;
    background-image: url(ie_page_background.gif);
    background-repeat: repeat-y;
}

PS: I'm using 2 stylesheets, one for all browsers and one made for IE.

Thanks!
