Is there a configuration option for "stop annoying me with popups for third-party products whenever I start Parallels"?
At the bottom left of the popup there is a button with words saying something like "do not show me again". I think checking that button will do what you are requesting
Thanks megavolt17. The pop-ups are so annoying that I've never bothered to look at them long enough to notice the "leave me alone" button. Next time I'll look for it and see if it really does anything.
