Hi, not sure if you have exactly the same issue but let me describe to you our problem. We have windows 7 64bit PCs running Creo 2 and we all share a common linux file server. We noticed this problem 2-3 months ago, where some users used to create or delete files/folders and others couldn't see those files/folders being created or deleted (inside Creo 2) unless they closed creo 2 and opened it again. All of us have the file server as a mapped drive and through windows explorer everything looked ok. It was like the folder refresh inside Creo wasn't working at all. What solved our problem was to disable the offline files from Windows 7 control panel. As soon as we did that and restarted our PCs everything worked fine. Maybe some issue between windows and samba server compatibility?? I am not sure if or how Creo 2 is involved in this issue.
