No WYSIWYG-Editor (FCKeditor) after IE-Update (IE9)

- edit the file /system/workplace/editors/fckeditor/editor_configuration.xml

- add the line to <useragents>

  <agent>^Mozilla/5\.0 \(compatible; MSIE [9]\.\d*; .*\)$</agent>

- save and publish the file

- reinitialize the workplace or restart the servlet container

It would be nice to hear if the editor works after changing these settings.
