Hi. Recently I had to make a project in IE 5.5 too. IE 5.5 throw almost instantly error. I have downloaded the developer version and try to figure out what could cause the errors.
By commenting out line 2167: div.appendChild( document.createComment("") ); and removing <select></select> from line 3122 jquery works perfect. But I am not sure these changes are safe. I need sy comment. Thanks in advance.
