Hi,
It is always possible there is a bug. Microsoft is constantly updating things.
We have two options if this happens again.
1: We can send you a special logging version where once you see the problem, you could send us the log. (preferred)
2: We can have a Windows developer remotely access your PC to do a little testing and hopefully find the problem.
Please let us know if this is still happening and we'll send you a logging version where you can send us the log when this happens again.
Thank you for taking the time to report anything you feel could be wrong so we can have an opportunity to fix it.
