I'm using jquery.validation.js plugin. It works fine in firefox. However, in IE, I have problem if there is errorred fields (which shows an error sentence). If it happens, the plugin keep onfocusin the first errored field (i use the event object to find out the problem). It should be logically wrong.
But it creates big problem when I then trigger e.g. an autocomplete, or rating section. it seems that IE does not know which field it is focusing and make the problem.
