Regarding the first issue, can you please provide more details on that? It will be best if you can open a new support ticket (you cannot attach files in the forums) and send us some screenshot showing the behavior in your application with the default editor and the RadEditor control.
As for the second problem - thank you for bringing it to our attention. I logged it in our database and we will investigate the reason for it and provide a fix if possible. Your points were updated for the report.
