This is text inside of the 'outer' div
Clicking 'Start' will grab the width of the 'outer' div (with the orange border) and display it in an alert box.
After the alert is dismissed, that width value will be assigned to 'outer' via $('#outer').css({width: theWidth}); (so nothing should change).
The trouble in FireFox is that sometimes this will cause the text to wrap, even though the width hasn't actually changed.
In ie, if you continue to click 'Start', the width will be reduced with each click.
