I'm still trying to resolve a possible issue to do with the Spyder 3 and it's ambient light sensor. I'm interested in the value of "hwver" in the output of a "-D5" debug trace from the Spyder 3 Pro, and Spyder 3 Elite devices. You can use any of spotread, dispcal or dispread to create a debug trace. If anyone with one of the above instruments can mail me the above value, it will help me solve the issue. Thanks, Graeme Gill.
