[Samba] mac os x & samba: refresh problem

[Luca Ferrari]

Hi all,
is it possible to force a refresh of Samba shares opened from a mac osx? If 
two mac users work on the same share and put files in it, then the other user 
cannot see the former's files until reconnecting to the share. I've tried 
even with a Finder-Refresh extension, but it does not work. I believe this is 
a more related OS-X problem, but I hope someone else has experience in this 
area.

Thanks,
Luca
