Thanks for asking us about this. We do know that this can happen and have logged a bug about it, but unfortunately we have not been able to reliably cause the problem to happen in-house and that makes it difficult to try to fix.

Closing all results doesn't always cause a null-reference exception here -- if you can make this happen all of the time, I'd be interested in seeing your computer configuration, maybe the answer is in there somewhere.

I cant't do this all the time. This happens not very often. The error occurs 2 times and i can't say why or when the exception occurs.
I will try to find a way to reproduce the error.
