Bonnie,
As I said, I don't use copy protection schemes. They only serve to keep honest people honest, hackers who want to make a copy will figure out how and do it. So, in my opinion, the only poeple that copy protection affects are the ones who wouldn't make the copy in the first place, my good clients. And coipy protection is an inconvience to them that I don't wan them to have to dela with.
If someone copies illegally one of my applications I will fight them in court if I have some appreciable loss due to it. If I have no appreciable loss I won't waste my energy worrying about it.
My message said that "If I ever was to use a copy protection scheme, I would use the dongle", why, because IMO it is the least obtrusive of all of the copy protection methods.
