Mail Merge in Microsoft word 2010 with NVDA, an Issue


Hello everyone,
I once tried using NVDA to perform a mail merge in Microsoft word 2010 and was successful. However, I've found an issue with the type new list dialogue box used to enter a list of recipients. As I tab through the type new list dialogue box, NVDA fails to read the names of the different fields, and I can't add a new entry for each recipient simply by using the keyboard. How do I solve this issue? Any help would be appreciated.
