Has anyone else had this issue? If I have Mac Mail in a secondary monitor and hit either reply, reply all or forward, Mail unexpectedly quits. The workaround is to move the mail window to the main monitor screen, then it works fine.

Hi there, cm-nzl!
Thanks for reaching out to the Apple Support Communities! It sounds like you have an issue with your Mac crashing when you use an external monitor and have the Mail app on the screen. Since the issue is not happening on the main monitor, we recommend taking a look at this article with steps to follow for How to use safe mode on your Mac. This will perform checks and stop certain software from starting up automatically. Once you are in safe mode, test to see if you have the same issue.
We also suggest follow thing these steps to Set up users, guests, and groups on Mac and create a test user to see if the issue is user specific or system wide.
Let us know the results and have a great day!

Actually. It's just started happening again. Nothing else has changed since this morning when it was working. I suspect it is trying to open the reply window at an invalid coordinate and causing the program to crash.
Thanks Jeremy,
Yes, the problem stopped after starting in Safe Mode. I have now restarted into normal mode and the problem has gone there too!
Thanks for getting back to us, cm-nzl!
We're glad you were able to resolve the issue and wish you the best!
Cheers!
