Rather than continue spending time on an issue I can't resolve, I want to completely wipe Blender from my computer and reinstall it as if I'm installing it for the first time.
Steps I tried:
I selected "Load factory settings", but Blender stayed the same.
I dragged the Blender folder and zip file to the trash and Securely Emptied Trash, but when I downloaded and installed a fresh version from the Blender site, Blender still had my old settings.
Still, Blender opens with all my old settings. How can I remove all traces of Blender and install it totally new?
