<key>CSCvg07375</key> Fixed?! What release?
Dear support team, certainly it's my own limited understanding, but I'm really confused by the &quot;Status: Fixed&quot; and the fact that there are simply no fixed software releases for this bug. This seems to be logically inconsistent. Can you advise?   Also it'd be really helpful to know the status of 7.0(3)I7(1) in regards of this bug. Best regards Stefan
