File is in use (NTx95)samba cvs

[Newman]

Dear Friends:
	I have a strange problem here with samba last cvs.
	I am using samba in very hard prodution and it is amazing!
	I have a system running simultaneous with 5 or more people sharing 
many files(DBF), everything woks ok when the clients are win95 or win 
98, but when the client is NT, the application tells that file is in 
use, and give me a error. It was not happening in older versions of 
samba.
	It seems that nt open the files on exclusive mode.
	Can someone help me?

	Tks,
