At first the classic version of RadEditor for MOSS started as RichHtml editing enhancement in SharePoint list items, only when it was not provided by the OBB editor. For example in different than IE browsers. This was limited by Microsoft. Later there were a lot of request for enabling the editor in IE as well, so we added the "Use RadEditor to edit List Items in Internet Explorer as well
" feature. It is our opinion that having two features for enabling the editor in different browser leads to inconstant and inconvenient user experience. When the ASP.NET AJAX version for the cotrol 5.x
was released, we could (the limitation by Microsoft was removed) implement only one "Use RadEditor to edit List Items"
feature, which we believe is the better user experience.
Indeed in you case you prefer the old functionality, but this is not the case with the majority of our clients. Unfortunately currently the only way of achieving the functionality is to create you own custom version of RadEditor for MOSS wsp solution and implement the features
for different browsers you self. The source code of RadEditor for MOSS is provided on demand and if you decide to create a custom solution, you can ask for it in an official support ticket.
