'Cursor jumps to top of the text edito' (http://www.telerik.com/community/forums/sharepoint-2007/full-featured-editor/cursor-jumps-to-top-of-the-text-edito.aspx)
and 'Upgrade messes up html' (http://www.telerik.com/community/forums/aspnet-ajax/editor/upgrade-messes-up-html.aspx) middle of page
I am having the same problem and would like to know if this has been fixed. If so we will upgrade our package.
I have a client whose .net app contains the editor complaining about this issue.
