my website, http://www.steveredshaw.free-online.co.uk, has an index page made up from a top row frame and 3 column frames set at (20%,*,20%)the middle frame for some of the pages loaded into that frame displays a horizontal scroll bar, but only in IE, not Firefoxthe content of this page does not exceed the frame width at the screen resolution I am using - so why is there a horizontal scrollbar in IE?
