problems with oplocks = false in 2.0 beta version

[David J. Reiter]

Hi Everybody,
 I seem to still be having problems with the caching of files on the
PC. I have tried to set the oplocks = false variable in the smb.conf
file but that has not seemed to help. Here is what I do to see the problem
Open a file on the PC, the close it.
Go to a unix machine and modify the file. 
Go back to the PC and re-open the file. I will get the old copy of
the file for a few minutes. Eventually the new one will show up,
but I dont want to have to wait. I am including the output of
the testparm in case that will help.
  I also just noticed that when I decrease the file size the PC
will only show my part of the original file. So if there were 
50 characters originally but now there are only 10 characters I 
will see only 10 characters when I re-open the file, but it will
be the first 10 characters of the old file, not the new one.
(At least for a few minutes) 

 Thanks for any help, or pointers,

David.
