Well, I finally got around to upgrading my well behaved version 9.0. And... Weird problem.
When I attempt to import files from ..\My Music folder (one that I always initially use and rip to, before moving files to other folders), 10.0.130 finds about 2,776 of what I can only describe as ghost files (after the scan results say 448 files scanned and 2,776 found!). They might have been there once but have not been for a long time. Clicking on them gives a dialog saying they cannot be found. They appear with the Red X next to them. Most are located (correctly, that is, where I pointed to scan) in the My Documents folder, though some are in a Z:\Full Albums2 (I have no such drive or folder) folder or a weird location e.g., Audio CD (3)\Temp\Post CD's\.. or Audio CD (3)\Radiohead.. These last "Audio CD" do not have a Red X next to them...
I delete them from the library only, but on re-importing they all reappear. This only happens when I scan ..\My Music\ folder. I have attempted to Clean Up the library, but this does not help.
