I've got an empty WPF app with only a RadRichTextBox in there.So my XAML looks like:
1. I run the application.
2. I type "bug" to the rich text box.
3. I double click on the word "bug" to select the whole word (double click it with mouse, do not select with keyboard)
4. I press Shift and I keep it pressed.
5. I start to type "BUG"
After "U" is typed I get an InvalidOperationException.
Do you have the same problem? Do you know is it a known bug? Is there any fix expected to it?
My build version is: 2013.3.1204.45
