I've been using Atlantis for printing envelopes lately and after I get done printing some the program automatically deletes my information in the delivery address box. It should not be doing this. I can see this happening if I completely close the program but I'm not doing that. All I did was print my ten envelopes and when I got done and I called up Tools and Envelopes, I saw that the Delivery Address box was blank.
Do you run multiple copies of Atlantis concurrently?
By the way, you can add the delivery address to an address book in Atlantis. Choose the "Tools | Address Books..." menu command of Atlantis, and edit an existing address book, or create a new one.
