Disable the midlle mouse button opening the Menus and Wiindows display on Gnome

I really want to dissable that. its very annoying and useless to me if someone could enlighten me as to how I can disable it that would be great. Thanks!

Hi
Not sure I understand what is occurring, for me the middle mouse button is used to paste? Have you perused Settings -> Tweak Tool under Keyboard and mouse and the Windows settings.

Maybe a bit more detail on how/when you see this.
