I went ahead and tried the Mac version stated on Page 1 (sorry, didn’t see it earlier) and have observed switching between projects while still in Cubase (not having to quit the program EVERY time to avoid a crash) to be much more stable! Only had one crash so far when importing audio which seemed to be a fluke but so far, so good!
MAC USERS THIS SEEMS TO WORK: defaults write com.cubase.common GraphicsAcceleration 0
