Sometimes when switching documents with ctrl + tab or when in the solution explorer and hitting enter to open a document NVDA starts making the error noise repeatedly.
Alt tabbing away from the application and back will stop NVDA from making the error noise. Otherwise it usually does not stop making the error noise.

In the nvda log this error shows up repeatedly:
LookupError: No such position

I have attached the nvda log to this ticket.
