I have been using Parallels 10 and WinXP as client without any issues. I need XP to run one only important program to me. Since Catalina and Parallels 10 do not behave well together, I am trying Parallels 15 with good results except this: When in coherence mode - that I always have on - I cannot turn off WinXP. I have exit coherence and only then turn it off. Assuming this does not happen with newer Win versions, it seems a minor glitch and nobody cares to XP anymore, but this is a nuisance I did not have... Any ideas?
