As the subject line says, Nikon View 6.2.7 doesn't work with XP SP3, at least with my D1H. My computer automatically updated itself to SP3, but after installing SP3, Nikon Transfer can't connect to the camera and quits with a message saying that there is no card in the camera. Uninstalling SP3 (from Add and Remove Programs) gets everything working again. The D1H connects via a firewire port. I don't know if cameras that connect via USB are affected.
