Duplicates: T25868
In the Link or Append file browser are only shown the autosave files
named .blend1 ...
The normal .blend files don't show up, but in Finder the exist and I can open and
work with it without problems.
Even already linked files don't update when I change the linked file and open
the main file again.
I work on a Macbook Pro with OS X "Snow Leopard" (latest update) and
Blender 2.56a.
