I am also a member of Smartboard Revolution, which is a GREAT place to find Smart Notebook lessons for Music, k-12 (see link below) as well as lessons for any grade level/subject. These lessons are great, because they can be used even if you do not have a Smartboard; the kids can use them on individual computers, or you can project the lesson onto a screen at the front of the class and run present the lesson from your computer.
Recently on a message board, someone posted the question about issues using Sibelius software successfully with a Smartboard. Has anyone else had found a solution to the sluggish performance and the formatting/ locking up issues? Has anyone found other software that works BETTER with Smart Notebook software?
