I can usually copy a worksheet across to another spreadsheet. Now, when I try, LibreOffice stops working. I have just downloaded the latest version to see if it helped but it didn’t.
I am using Windows 7 on my laptop.
Maybe an issue with the user profile, test resetting it.https://wiki.documentfoundation.org/UserProfile
Thank you for your suggestion. I looked into it but it seemed far too complicated for my poor old brain. I decided to uninstall the whole thing and redownload the program. I downloaded LibreOffice Still and it now seems to be working normally. Big sigh of relief…
