LC 8.1 Mac - Crash on name change

[Graham Samuel]

I just opened a ‘legacy’ stack (LC7.x format), made a few changes, and tried to save it as an LC8 native version in a new folder. I got several warnings that the stack was already open - seemingly inappropriate - and then LC crashed. I reopened it and my new version had been saved, but not the changes I made.

This is all on a Mac running El Capitan 10.11.6

This looks like a bug to me, but I just wonder if anyone has experienced anything like this before I report it.
