I've also been trying to find a way to remove unwanted time signatures, and I appreciate the above advice, but when I select "Score", the only options I can see are "Settings", "Parts", "Auto Format", "Insert Bar" and "Append Bar". Can someone please tell me where I find "Set Time Signature"? I'd like to think that, if I could have seen that, I would certainly have tried it, to see if there is an option for setting the repetition of the time signature!! Thanks, Rog.
