I am using Ajax to provide dynamic HTML SELECTs in what is a very static legacy web app. I build the SELECT/OPTION tags using the DOM api. I set an attribute on each SELECT to point to an 'onchange' event.
Everything works fine until I port to IE7, in which the events do not fire. It works correctly in Firefox and Safari.
Does anyone know of a work-around for this odd IE behaviour?
TIA...
