How to save?

Hi - I like the game, but I can’t figure out how to save. Fortunately the autosave works, but I am not getting any option to save individual games. If I hit the Escape key or the Quit button, all I can do is return to the main menu. What am I missing?

Thank you for any help.

when you return to the main menu during a game, a picture of a floppy disk appears along the bottom. Click on that to save.

For some reason I just couldn’t see that last night. Thank you for the help.
