Items missing from File Menu

I just downloaded DVR 15 and opened a project as a test.

But when I wanted to close it I noticed there is no File - close project menu item, the file- switch project item also isn't there?

Why are these menu items not there? I can now only close a project by closing the application.

How can I correct this?

The Close Project and Switch Project menu items are only available if you activate Dynamic Project Switching which keeps opened projects in memory. Otherwise a project is automatically closed when you open another project through the Project Manager.
