Hi Barry just thought you could use some positive feedback as well. I just uninstalled 10.2 and installed 10.3 it even kept my location details and started in less than 5 seconds it used to take upto 30 seconds to start with 10.2 very happy so far and I think you provide a brilliant and free resource to us. I have included details of my system in the hope that it assists with development and planning and showing what specs are good for your software.
