Internet Explorer error

Did u put this in the head of your document?
<script>
function FCKeditor_OnComplete( editorInstance )
{
var oCombo = document.getElementById( 'cmbSkins' ) ;

// Get the active skin.
var sSkin = editorInstance.Config['SkinPath'] ;
sSkin = sSkin.match( /[^\/]+(?=\/$)/g ) ;

oCombo.value = sSkin ;
oCombo.style.visibility = '' ;
}
</script>

If you did.. take it out. u dont need it

You might want to try loading in some default text. I was having an issue of the toolbar not showing up if there is no default text in the textarea. I solve this by putting in a &nbsp; or some simply directions that can be easily deleted.

I just tried the online demo with one of my windows 2000 servers and it worked fine!

My user agent string is exactly the same as yours:

Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; .NET CLR 1.1.4322)

So maybe hacking your user agent string didn't solve the problem?

Wow that's weird ... I've never seen an IE USER_AGENT string without a version number.

I was getting the same error - broken in IE but worked in Firefox. Tracked my problem down to having an extra comma in my custom toolbar, like this:

FCKConfig.ToolbarSets["MyToolbar"] = [

['FontFormat','FontName','FontSize'],
['Rule','Image','Link','Unlink'],

] ;

was this resolved?

Im having the same problem. Works in FF not in IE. Same JS error.

However the online demo does work. I am using the default fckconfig.js.
