[Samba] Excel files locked for editing periodically in SAMBA 2.2.8a?

[Paul Apking]

This is happening periodically on our network with users using excel 
documents. Either with Office 2000,XP or 2003. The problem seems to 
happen for a day or so then disappear for a while again. I've read it 
might be the version of Samba we are using?  If so, is there a 
workaround that we could try until we upgrade in a couple weeks?

Regards,
