That was too easy...I too have struggled with thise. I have been copying systems one by one from one FL to to a new FL in order to get a new name for it. Duh. I even tried text editing the datafiles in raw format with no success. Thanks for replying!
One thing to keep in mind, your scanner will not "delete/modify" the old one, but will be added to your Favorite list unless you clear all the favorites when writing to the scanner. You have to go into the scanner and delete it from there.
