Immediately when you ctrl z, 3ds max error message: “Application Error. An error has occurred and the application will now close. Do you want to attempt to save a copy of the current scene?”

 

Next a pop-up window will automatically back up. Also, when you exit 3dsmax, you do not choose to save the file, but the file is still saved, this will cause many unintended annoyances.
