Parallels 5 OS X 10.6.1 I have jpg files on an OS X drive which I share in WinXP. I can copy such a file very quickly from the drive to my XP desktop. When I try to open it from WinXP using PReview, however, it takes 6 seconds to open the file. I can copy the file to the desktop and open it from there in less time. Anyone have any ideas why it is so slow?
