Debian 7.2 Samba version 3.6.6 Windows 8 Excel 2013 Problem

Hi Guys

I have been trying to solve this problem for some time now and i'm just not getting to the bottom of it.

I have a 3 user network with Windows 8 64bit pro and Office 2013 home and business. The Excel files are beeing shared by a Debian Samba server. Debian 7.2 Running Samba 3.6.6. The server has got all the latest updates installed
The desktops has got the latest windows and office updates installed.

Problem:
When the users open excel workbooks that are located on the samba share "company" they can open up to a maximum of 3 to 5, then the next one will be a blank workbook. All the workbooks has got the xlsx extension to the file. They then have to close all the other workbooks to be able to open the last one that was blank witch then opens fine.

smb.conf:
