Could you please describe your scenario with a little bit more details? A step by step instructions will helpful as well.
If you have the full 5.x.x version of RadEditor for MOSS, you don't have to use Lite RadEditor for MOSS4.5.6. Here are the reasons why:
1. The Lite version does't have the full functionality.
2. The lite version is based on the classic ASP.NET RadEditor (http://demos.telerik.com/aspnet-classic/Editor/Examples/Default/DefaultCS.aspx
) and not on the ASP.NET AJAX version of the control (http://demos.telerik.com/aspnet-ajax/editor/examples/default/defaultcs.aspx
2. We stopped enhancing the Lite version in 2009 so it might not work as expected in the latest versions of the browsers.
All the best,
