I recommend submitting program log files by navigating to Help > Report a problem in the upper menu at the top of the screen. You may then include a brief description of the issue as well as any available screenshots you may have along with the data logs. Although we will investigate this issue further, we do not have an ETA on a resolution, and you will not receive a response through these submissions, as these are used purely for investigative purposes.
