Hi,
Thanks to Claude Marinier, Carl Perkins and Jan-erik Söderholm, who gave me the idea of adding a time-out feature in the directory memory cache.
I added that feature (30 seconds validity for the cache), and it looks OK : no loss in performances, and now the outside changes such as renames are seen on the PC client within 30 secs.
Will be available in the next release...
