Double margin bug in IE6

Are your containers not where they're supposed to be in IE6 but fine in all other browsers? You've possibly caused the double margin bug to appear.
Fix it by resetting the margins to half of the previous value:

Main stylesheet
margin:10px 20px 5px 8px;

IE6 stylesheet
margin:10px 10px 5px 4px;

The double margin only usually affects the left and right margins.
