This is on Windows 7 SP1 x64 Professional with IE9 (all latest updates installed) and SP V18.104.22.1688.
If I right click on the SP icon in the Notification Tray and select Help, none of the website links in the Help menu work. Clicking on Online Forum, Web Site, or Report problem with web site does nothing. The URL links on the About window do not work either.
