On my computer, I have both a Lion and Snow Leopard volume. On my wife’s computer, there is only Snow Leopard. 1. My wife and I are connected via Airport Extreme wifi/home network. I can see her HD icon on my desktop and vice-versa. 2. I can drop folders & files on her HD icon, and voila, they appear on her machine. 3. When my wife accesses my Snow Leopard volume (via Finder/Go ->Connect to Server) she has no problems dragging and dropping. But when she accesses my Lion volume, she is always advised that she is forbidden: “…lacks permission…” and thus cannot drop & drag to my computer. We both have File Sharing enabled in System Prefs/Sharing. In short, all is fine when we both use Snow Leopard, but not when I am using my Lion volume. Is this a Lion bug (feature) or Operator Error? Is there a fix?
