I have been using Sibelius notation software for years now. I think its a great package. It can most things well and there is usually always two ways to carry out a task.
Its a large package though and I am still learning things I didn't know. I have found there is just no way to put in a wavy slur line. The only way to do this is by using graphics and importing them.
Today I was working on a large score and I decided I wanted two blank pages at the front (one for the title one for notes to the score. I somehow ended up with three pages. There is no obvious way to delete the spare page. Undaunted I thought the best thing to do was to change the number of pages from 3 to 2 - seemed logical? Err no Sibelius added another two pages so now I have 5 pages (3 of which I don't want).
I can really recommend the Sibelius help forum. I posted my problem at about 5 pm and by 7 pm some kind person had replied with the answer. Brilliant
