Printing envelopes in Address Book

I searched this forum and could not find and answer to this problem. I was trying to print an address on an envelope. Address book would do nothing the first time I tried. The second time, it invariably crashed. By doing a web search, I found that this happens when you don't have your own address entered on your card -- Address Book can't find the return address to print and gets unhappy. I entered my own address and the problem is solved. Perhaps this post will help someone in the future.....
