After a Windows 7 "Update", (not sure which or when), my on-screen keyboard popped an error when I tried to use it: "A referral was returned from the server." After looking online for too long, I found Microsoft saying "Try to see (by trial and error) which update is causing it." ?? Not an answer. I was hoping for "Oh, uninstall this update." Neither was System Restore a good option. Finally found what worked after seeing ALL (on-screen keyboard, magnifier, narrator) had the same error. Finally found what worked, was shutting off User Access Control. That worked for me since I'm not a newbie, but may not work for others that are.
