Manual breaks vanished, insert option doesn't work

Manual breaks in my document have vanished and the insert option only moves the cursor down. What can I do?
Thank you

Hi Anon, Can you upload an example document? Is your problem reproducible on other documents?

It sounds like they are actually causing breaks (since you say they move the cursor down), but you’re not seeing what you expected. Perhaps you need to turn on ViewNonprinting Characters in order to see the breaks you’ve inserted.

Alternatively it could be that you’ve selected ViewWeb Layout and need to switch back to ViewPrint Layout in order to see page breaks etc.

I have the same problem. I turn on “Insert - manual row break” and the thin blue line shows above the row selected. But in preview Calc still shows my 156 row SS as a single page with unreadabley small characters. Calc help says that “true” page breaks show as “black” - I cannot get this. How do I get Calc to accept my manual page beaks as true, printable page breaks??
