How many opportunities to find stolen copies do you think you'll get in your lifetime? How much will it cost you in time and dollars? When will you get time to do any useful work? Forget it - it isn't worth the effort. I wrote a program called the Chrome Ranger in 1982, dutifully copyrighted and "execution" protected it, and sold a few thousand copies through IBM dealers. The protection, such as it was, did little to deter copying and definitely reduced sales, especially to the hard-disk crowd. I now sell the program without protection and find that it sells itself on the basis of stolen copies. Free advertising, in effect. Sure I lose some sales, but I make some that I might not otherwise, so I still come out ahead. Now I have time to write new programs instead of chasing after crooks, who are usually 14-year olds that I can't or won't prosecute anyway. Augie Hansen Omniware Denver, Colorado
