I have been using your excellent validation script for some time
without any problems, but have found a problem when using the latest
versions of browsers. IE7 beta, Opera 9.0 and Firefox 1.5 all have the
same problem and yet IE6 and IE5.5 work perfectly.

There are no errors reported but when multiple items in a multiple
select list are selected, only the first selected items is actually
passed across. It doesn't matter whether the form action is GET or
POST, still only the first selected item comes through.

If I comment out the call to this.setup(); in the code then the
multiple values do get passed across without problem so this is
certainly caused by something in the script.

Any suggestions would be most appreciated.
