samba - Jul 2007 - Excel - share Access Denied after opening file

I have a strange problem with Excel + Word from an XP Pro (SP2) PC to a 
Linux Samba share (HOME).

If I 
1 - open Excel,
2 - then open a file on my Samba share HOME,
3 - any subsequent attempts to save or open a file on the HOME share
immediately result in an 'Access Denied' windows error message 
as soon as I select the root of the HOME share!

The same thing happens if I open a file from anywhere else 1st.

I am just using Workgroups - no Domains.
The same thing happens if I have Windows simple file sharing enabled or 
disabled.

I have tried amending various Samba options (using SWAT).
e.g. 'nt acl support', locking, dos filemode/filetimes.

There are no error messages in my samba logs or Windows Firewall.

All Windows Explorer activities work OK.


I have one other Samba server running on my network - a Linksys NSLU2.
I can successfully access shares on this device when I am denied access 
on my HOME share.


Does anyone have any idea what causes this - or how to fix it?

I fixed this simply by updating to a leter version of Samba (3.0.25).
