Hi Jo,
I'm sorry you had to re-create the project file but from your more detailed descriptions and the information about view settings not being saved, it sounds likely that your project file did develop some corruption.
I know you've resolved the issue, but you could try a test. Save the project as an XML file and then re-import (open) the XML file as a new project. Then see if you can save the view changes to the Task Sheet.
