I can't get rid of it. Somehow it got turned on and there is no way to remove it, ever, except to stop toolbox altogether. I don't know what it is, I don't care what it is, I don't want it and I can't get rid of it.
Going into the Presentation Mode tool and unchecking the "Autodetect External Displays" option in Presentation Mode settings is supposed to keep it from doing this, however it doesn't. I have become convinced that Parallels intentionally engineers toolbox to be as intrusive as possible and now I set the entire toolbox app to no longer start when my Mac starts up because I am suspicious about what information they are collecting. Their tools constantly ask for permissions they don't need. Parallels itself is useful and somewhat of a necessary evil for me, but I don't care for their business practices.
