i'm developing a website in DW8 and at this stage i got front alomost page designed. Its got two columns, one is used for navigation buttons the other one for page contents, also i got a banner on the top of the page and a footer at the bottom. all of this is wrapped in #wrapper. by some strange reason horizontal scroll bar has appeared and there is about 20px of white space between the edge of #wrapper and the edge of the window. i have #wrapper width set to 100%, all margins and padding values are set to 0. could somebody help me with this?
