My secretary had this problem, and now I am getting it. I rebooted her client and now her PC is "Filing" fine. Now mine is not. Don't know what to make of it all.
When I reboot the client, I do realize that they are being filed, but it just doesn't disappear from the GUI, until reboot.
Odd that .. unless the client has disconnected from the server ... but then it wouldn't be filing. Reproducible?
Happened on one of my PC and my secretary's PC. I'd say pretty reproducible. I can just restart the client and all is OK. I'll let you know if it persists.
