I am using this control in an application and it seems that one can not use the TAB key to indent the text with this control. As soon as the Tab key is pressed, the focus of the program is set to the next object on the form.
This is a little frustrating, because most users instinctively use the TAB key for indentation.

Is there a way of avoiding this changing of the focus when using the TAB key?
