Reply To: Documentation editor causes crashes

I have experienced several crashes that I have narrowed down to issues in the documentation tab. I primarily use data flow diagrams and sometimes use multi-line descriptions in the documentation. I have had it crash with the following errors:

System.NullReferenceException: Object reference not set to an instance of an object.
