Just finally updated to LW 4.10.9 from whatever I had been using in Classic (4.0.10, I think). I have a lot of files that I can share, in the same folders with files that I do not want to share. To get around this in Classic I made aliases for the shareable files and put the aliases in a folder, which I specified as a shared folder. The old LW apparently recognized the paths to the original files, as some of them were successfully dl'd by other users out there.

Dunno if it's an OS X thing (OS X 10.4) or a LW 4.10 thing, but now the aliases in my shared folder full o' aliases are not recognized as shared files.
