Arduino 1.0 USB driver version

I have some USB driver problems and they may or may not be related to the FTDI driver itself.
What confuses me are the reported driver versions.
I had Arduino 23 installed and on XP (Win7 reports the same) the USB driver would report:
Driver Date: 15/11/2007 Driver version: 5.1.2600.0

The driver folder in the Arduino 1.0 folder appear newer however when trying to update windows refuses and reports them to be the same.
Even a manual USB driver removal and a brand new install with the new drivers in Arduino 1.0 will still report the above properties.

When i check the FTDI site http://www.ftdichip.com/Drivers/VCP.htm the drivers there are much newer showing 2011-04-12 for version 2.08.14

Why are there 2007 drivers in the arduino download and how do I ensure I use the most stable driver available????

Any help is greatly appreciated!!

I have not found any answer on why the driver version reports 15/11/2007.
Anybody?

The driver version you are referring to comes from the .INF files in the Arduino drivers folder.

Here is the relevant section from the .INF file that determines the version:

[Version]
Signature="$Windows NT$"
Class=Ports
ClassGuid={4D36E978-E325-11CE-BFC1-08002BE10318}
Provider=%MFGNAME%
LayoutFile=layout.inf
CatalogFile=%MFGFILENAME%.cat
DriverVer=11/15/2007,5.1.2600.0

This version is for informational purposes only and really has nothing to do with the actual Windows driver that does the work. The Windows driver that is used is USBSER.SYS . The .INF file simply instructs Windows to use the USBSER.SYS driver whenever the Arduino device is connected to the system.
