CMS Made Simple Forums

I installed cmsmadesimple 1.0.6 on my webserver(centos php4).
Everything is set to default settings.
FCKeditor doesn't work on IE, it throws a js error.
But on Firefox, everything is OK.

I reinstalled the same verion on my laptop(macos php5), I works well both on firefox and ie.

Does anyone know why and how to solve?

I always recommend people to use Firefox as IE seems to have more problems for some reason.

What version IE?

If it's 7 it may need some tweeking on JS settings (if you haven't already tried this)
