samba - Apr 2007 - Deleted files reappear after login

Hi,

problem is, if someone deletes files e.g. from Desktop in XP, logs out 
and logs in again, the files reappear.
They are not deleted in the profile on the server.

The profile is syncing so that changes to files and new files are ok.
Only deleting does not work.

am using:
Redhat EL4 U4, Samba 3.0.24-SerNet-RedHat, XP SP2 Clients.

smb.conf parts:

         logon path = \\%L\profiles\%U
         logon script = login.cmd %U %G
         logon drive = h:

[netlogon]
         comment = Network Logon Service
         path = /etc/samba/netlogon
         public = no
         read only = yes
         writeable = no
         browseable = no
         valid users = @xyz root

[profiles]
         comment = Roaming profiles share
         path = /shares/profiles
         writeable = yes
         create mask = 0660
         directory mask = 0770
         browsable = no
         valid users = @xyz root
         force user = %U
         profile acls = yes
         hide dot files = no
         csc policy = disable

Any ideas?

Thx
Rainer
