I'm afraid I am not quite sure what you mean.
When you say that the ribbon is selected, are you referring to the same scenario - when a table is inserted or modified, for example? If this is the case, can you please share with us whether you are observing the same behavior in our demos
. We would appreciate some steps that can help us replicate the issue, as I did not manage to do that. In case you are observing the explained behavior only in your project, please share additional details about your setup.
Generally, we are aware that particular setups cause loss of focus of RadRichTextBox, for example clicking on a style in the StylesGallery. This is already on our to-do list and we will do our best to fix it as soon as possible.
I'm looking forward to your reply with further details. Thank you for your cooperation.
