Parallels went from being the best piece of software I ever owned to one of the worst. I'm a simple user. I just ask that my copy and paste work properly as I use Windows remote desktop when accessing my work servers. That doesn't work well anymore. And the final thing I loved, I was able to create a quick key (F6) to go back and forth from Windows to Mac. Now I have to have the Control Center window open? And the control center window has to have focus for the quick key to work? This can't be by design? I just ask that those two areas improve. We paid to upgrade the software. Not downgrade it.
