Thread:Project:Support desk/WikiEditor Problem in Internet Explorer

I've added Wikieditor(from old editor to new, the one used in Wikipedia and here) in localsettings.php, it works fine in firefox but the special characters function isn't showing up in IE. I've tried Wikipedia Editor in IE and it works fine there. How do I fix this.

System Used: Apache 2.2.21 MySQL 5.5.16 (Community Server) PHP 5.3.8 (VC9 X86 32bit thread safe) + PEAR Internet Explorer 8 Mediawiki 1.18
