I'm having the same issue with Dragon NaturallySpeaking 11/11.5 upgrade. It's something I've been wanting to blame on the website I had open (plantronics.com) but evidently that's not the case and it's happened seven times over the past few days. Would Thunderbird be a better avenue to take or at least to give it a try? Being that I've never used Thunderbird and I don't know anything about it, I'm more than just open to suggestions until a cure can be found.

Thank you much! Bruce
