Am running Parallels 9 under Yosemite on a newer MacBook Pro with an external Apple DVD drive. Am trying to install MS Flight Simulator 2002's 3 disks. #1 installs fine but asks for #2 but because the software takes over the full screen, I can't figure out how to eject #1 to input #2 (then later #3) to complete the install. Command+E doesn't work.
