Kirk, Same problem here with a MacBook Air recently upgraded to Sierra. The issue for us is that 4D crashes anytime a 4D Write area is touched. I am running Sierra on an iMac with no issues and thought it may be related to the laptop, however see the release notes for 15.3, what they state is consistent with our experience. Running 4D on the older build of Sierra 10.12.1 is fine, not so on the more recent build.
