This might be a silly question but can using the 3 common softwares of win500,psredit and arc500 damage the way the unit scans?? I wasnt happy with win500 or the arc500. I liked the psredit but used all 3 in one of my folders. I noticed strange scanning speeds on some systems,preventing me to hear a complete conversation without the unit jumping back to scan?? Should you stick with 1 type?
