Some of my users are having problems saving documents to their shared folder. They get a message about the file being in use even though it is not in use. I tried rebooting their computer and this doesn't fix the problem. They are running OS 10.4 and our server is running Windows 2003. I am guessing that there is a setting in OS X that sets a file's flag to "in use." Anybody knows how to correct this? Any help is greatly appreciated.
