Windows server shows open Foxpro files when none should be open

This is weird, Under computer management->shared folders->open files, I can see files that the server believes are open, listed with me having them open, after all my foxpro sessions are closed, even after  a refresh.   I know they're not open because I can open them exclusively with no error. They eventually go away, but it's 5 or more minutes later.  I'm using Foxpro for Windows 2.6 and Windows Server 2008.   I don't ever remember seeing this behavior before.   Any ideas?
