The makes sense. I have my PICstart Plus hooked up to my development PC and the ProMateII attached to a DOS machine for production programming. The windowed parts which I had the most trouble erasing (I persevered and they finally _did_ erase), were ones that I had to recall from the production department due to the last-minute discovery of a bug. :-0 The code-protected JWs made on my development PC took maybe an hour to erase. The parts from the ProMate took about 4. --Matt
