I have used PS-9, 10, 11, and 13. I have experienced very slow speeds and freezes with all my Organizer programs. I keep buying the new version hoping things have improved but to no avail. PS-13 has been the best but I still experience freeze-ups when I do certain functions. Unfortunately, I have not been able to figure out what those functions are so I can avoid them. I still have PS-11 and 13 on my MacBook Pro (Mid 2015 running 10.13.1) and have purchased PS-2018. I don't, however, want to just dump my old Organizer content into the new one in case it's carrying some sort of bug. I also don't know if I should uninstall PS-11 and 13 before I start with PS-2018. Can someone advise me the best way to set-up PS-2018 (especially the Organizer) to be sure I have a clean copy that's not carrying a bug from a previous version. Thank you.
I should have said in my first post that I'm talking about Photoshop "Elements" 13 and 2018. Thanks for any advice.
