This particular bug only seems to happen in ie6, when the window is refreshed and the current browser window size is smaller then the width of the content. For instance, if my window size is 800x600, and my content width is 850, on refresh in ie6, the size of the width of the element is wrong.

To see an example go to the jquery demo page:

http://docs.jquery.com/CSS/width

get document width() , returns the incorrect width

in ie6, when the window size is initially smaller then the content width and reload/refresh page. Tested against FF and ie6, FF returned a different width which seemed to be correct.
