The Problem
Recently I had to use the window object’s onresize event in a project I was working on. I needed it in order to reposition some elements on a page whenever the browser’s window size changed. The trouble was, the function was relatively intense and was causing IE to choke. The reason? Different browsers fire the event at different intervals. In Firefox, it fires only once the user stops resizing the window. In IE, it fires continuously while the user is resizing the window. This of course, meant that IE was trying to run my function once every millisecond or so.
