didi you try "right klick -> measure -> remove measure"? You may even remove a bunch (as from importing a midi with repeats played that you want to notate as repeats)!
Would you happen to know how to change the settings so I can place 5 measures on each line? I need it to be 5 on each line when I print it, it doesn't really matter how it is in the soft copy.
