Appreciate any help. On my old computer, Win ME, 1GHz, with Eraser 5.6, it took about 45 minutes to run its course. I now have Win XP, 3.2 GHz and Eraser 5.7. I figured the run time would be greatly reduced. Imagine my surprise when it took 2 1/2 hours. Does anyone have an explanation? Will going back to Eraser 5.6 help?
