I'm checking peripheral compatibility with the Vista 64 box I'm ordering. So far as I can see Nikon Scan doesn't work with Vista 64, so will have to get Ed Hamrick's Vuescan, which is OK except so far as a I remember (not used it for a while), the manual focussing facility for the LS 50 is in the Nikon Scan software and I won't be able to access this via Vuescan. Is there a work around?
