According to my information this issue has been resolved in a later version of OSX 10.12.1. After you update to a version equal to, or later than, OSX 10.12.1 build 16B2553a then this issue should be resolved. That build should also be called beta 5. Again thanks for reporting this issue. Jesper
Thank you for the crash log. We are looking at this with Apple. In the meantime, you may be able to get around this problem by going into Preferences>General and un-check "Show Messages". Jesper

Thanks for confirming Beta 5 solved your issue. Theory, let us know if you're able to update to Beta 5 and whether that fixes it for you. I suspect it will.
