Saving text file on SMB share - file has changed

Hi,

I'm having a problem working on a remote Samba share. When I edit a
(text) file on this share using gedit for example, I get the message that
the file has changed on disk when I try to save it. This is a problem in
Eclipse IDE also.

Normal access to the files is fine and they do save eventually.

The server hosting the share is Fedora 7, as is the client.

Interestingly this is not a problem with either a Windows or Mac client,
therefore I assume I am mounting the share incorrectly:

mount -t cifs host mount -o username=username -p password

(with smbfs is the same result).

Thanks in advance.
