If what Steve says is true,I understand.Like I said in my Original post,I LOVE POSER4.The fact that a serial number checker was installed without telling us originally was what got me upset,and I had EVERY right to feel that way.Reading all the other posts here and in a few other places I got the impression from more Experienced Artists that it was a Trojan.If that was wrong, then they are wrong, and they should "chill".BUT and I repeat BUT,it was WRONG to put it in there WITHOUT explaining it.THAT is what got everyone suspicious.It seemed like Curious was "hiding" something.Since Steve explained it wasn't on purpose,I choose to believe him,since, like I said,I do Love Poser4,and I am sure he is a decent guy.Just next time,EXPLAIN EXACTLY what is in a download.And to everyone else here,at least give Curious a chance.I know I will now.Everyone deserves the benefit of the doubt.I'm sure Larry,Steve,and Curious Labs all have our best interests at heart.So we should support them.
