@ua741 Hey, I am also intermittently running into the same issue. Were you ever able to resolve or get around it?

[clairernovotny]

If there's a way to repro this, I can look into it further -- just haven't seen it yet.

[srad123]

Will try to repro, but, not sure if i can repro it. I have seen it once in the last 6 months that i am using it. This is the exception call stack i got.
