Community Tags doesn't work in IE6

Issue Summary

When tagging through IE6 it returns a very weird tag called:
function(o){for(var i=0,len=this.length;i<len;++i){if(this[i]==o)return i;} return-1;}

Also, the AJAX doesn't work in IE6 for this module. Tags are not added when you press "Enter" or click "Add". For better AJAX that actually works in IE6, see a module called Active Tags http://drupal.org/project/active_tags
