--- Comment #32 from Gordan Bobic gordan@bobich.net --- This is a much older bug than the duplicate listed. However, I disagree that it is fixed until this setting is made the default and the registry key is instead needed to instate the old behaviour.
Unless this key is known to outright break something else, it should be the default because it's absence clearly breaks some applications.
