Same Problem over here ... the Error is reproducable in any IE-Version

[johndove]

Putting this meta tag at the beginning of each page using cooltips will make it work:
{meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" /}
(replace the curly-braces with tag brackers, of course.)
Not a fix, but a temporary solution.
