Hi Guru: I have discovered what seems to be a glitch. I'm not able to right click on items, like notes and measures. No drop down menu appears any any right clicks so I've been unable to insert double bars, unable to do page breaks, etc. I checked my keyboard and it successfully double clicks in other places on my computer, so I'm wondering if there is a glitch with Crescendo, right clicks, and Apple? I'm not on Catalina yet, maybe that will make a difference? Have you heard of anyone else with this problem? Thanks. Coming back, I just tried another keyboard all together. I'm just not able to get a right click drop menu going on Crescendo. This is kind of a major glitch. I hope I can figure this out!
