Re: Strange!!! (Is it the OVERWRITE????)
Are you basically saying that this could not happen?
Yes.

Well, I have no explanation of your problems. WinSCP has no cache for file contents, hence it simply cannot cause your troubles.
Answers to guest's question may give some hints.
Note that in some cases WinSCP may actually do "delete then create new", when you choose to overwrite. That's why you may not get the permissions errors.
Did Jane really copy up v3 successfully? Are you sure she didn't copy up v2 then the v3 updates -- for whatever reason -- never actually made it to the server?
Is the server's filesystem case sensitive? Are you changing the case when you up/download files?
What permissions errors does John encounter? Is the destination server unix/linux, windows, something else? Assuming *nix, what is the umask of you, Jane, and John on the server? What are the permissions on the directory where you're dumping these files? Does the log on the server side have anything useful to say?
If you replicate the exact same conditions with you using a different client, is the behavior the same, or different (and if so, how)?
