Parallels Toolbox Version 5.1.0, MacOS 11.6.2. Every time I log in, all desktop files are hidden and I have to unhide them. I can find no user setting to change this. I've contacted Parallels support, they suggested reinstalling Parallels Toolbox which did not help. Suggestions? This "on by default" behavior must be stuck in a preferences file somewhere, even if it's not a user selectable setting.
