Sarge it may be simple to you but please do not be so selfish and not see the other people's choices and perhaps abilities. Not everyone can OR WANT to change INI files and all in order to configure a virtual world.
So let there be CHOICES!
YES YOU CAN USE PREFERRED VIEWER WITH THE FREE VERSION. All you need to do is configure it. It is possible to configure the FREE version to do whatever you want.
It is a matter of choice! And if you do not want to configure it just get the PAID version.
I tried SIM ON A STICK and DIVA, I had to spend hours configuring it. I rather use NWS. Much simpler!
I give my full support to OLIVIER and NWS!
