On my demo site at monoforge, the FCKeditor displays correctly in Mozilla and Firefox but in IE it acts like a downscale browser was detected and renders as a plain textbox.  It behaves correctly on my Fedora Core 2 test machine running mono 1.0 in all browsers so I suspect the problem is in the mono 1.1.3 release. As I mentioned previously I also had worse problems on mono 1.1.3 with FreeTextBox. The mono team said FreeTextBox works for them but I suspect they are doing daily builds and have all the patches since 1.1.3 whereas monoForge has just the official 1.1.3 release. I'm starting to think that if we are going to use the developer branch on monoForge we should have frequent builds from SVN so that we don't report bugs that are fixed, otherwise we should probably stick with the stable releases.
