I'm currently running NT 4.0, Svce Pack3 mounted to a samba Sun box. I run an editor called "Codewrite" on the NT machine and occasionally this editor reports that the file I am viewing has changed by some unknown process and I should delete the copy that I am viewing. This has been going on for some time and have not seen it occur in any other network application. Has anyone ever seen this issue before; i.e. what appears to the application as a file being changed outside of the app. The files in question are always on the sun machine.
