I'll be frank with you, I have it working, and got it working again after a factory reset on the 2nd day, but I can't remember how I did it. I remember struggling to get it back. This has all been too fast, but trust me, it works as a Widget from some program, and you can set the update interval. This last week has been a blur for me, and not just because I got an Evo a week early. Some reasons are far more serious. But the answer will be forthcoming soon, perhaps from me if I can shake the Night Fever.......
