Strange thing keeps happening with one of my clients. They are running 3 iMacs 2of which are running 10.9.3 and 1 is running 10.9.4. While they are accessing a Windows share, they can be working away quite happily until it comes to saving where they no longer have access to the file opened from the server and have to save as a new file. They are accessing using smb://{servername}/{share}
What would cause this?
Cheers
