I've been using Lightroom for several years. When I upload my CF cards, I use Files>Import Photos From Device. When the dialogue comes up, under Copy To I can browse and select the drive (not C) and folder I want for my picture files.
I just changed from Windows XP 32 bit to Windows 7 64 bit. Lo and behold, when I do the same thing in Lightroom and go to browse to the the same disk and folder I have been using in XP I find that the only browsing I can do is on the C: drive! I tried right-clicking, left-clicking, and even hitting the computer with my palm a couple of times, but to no avail.
I have already synchronized my picture folders again, and updated my Lightroom library, so it has nothing to do with that.
And yes, I made sure that my several drives were accessible to Windows 7. One of them had to be "imported" using the storage management stuff, but I can browse all of my drives with My Computer or Windows Explorer, so that is not the problem.
Any ideas out there? I don't want to believe that this change is a new "feature" added by Microsoft.
