I notice that when I test 2016r4 on some Sample Applications in the Examples folder, it frequently crashes when I do one of these:
make a change in code somewhere
press the Close button to exit the Project without saving the change
make a change in code somewhere
press the Close button to exit the Project with saving the change
However, if I manually do a Save before exiting, this doesn’t happen anymore. I also couldn’t successfully create a Feedback case for this. I tried a couple times. I was either told the case couldn’t be created or the Feedback app went into an endless “Wait” loop.
Odd. I just got an email from Feedback that my was indeed posted as #45976, but I don’t see it in Feedback at all. Maybe it was posted as Private? I never choose that option, but maybe I did that accidentally.
