I have this bit of script to widen a text box on mouseover and shorten it on mouseoff.
The problem I am having is that Internet Explorer doesn\'t seem to extend it\'
Had the same problem, and WorldWidewebb's answer worked very well on IE8. I just made a slight change, removing "select" from the selector, since I included the select box's class in the selector. Made it a really simple fix.
Also, i had it implemented on a menu that uses the hoverIntent jquery plugin, with no problems. (No interference).
