I have submitted an update to Apple, currently pending approval. Hopefully it will be available on the App Store soon and fix the issues you're seeing. It's interesting that no matter how much one tests, bugs invariably appear for some percentage of users, given the configuration of the software and the environment of the machine. I liken it to manufacturing defects that present at so many sigma. It's because of feedback from users like you that things get better, so thanks for taking the time to comment!
