Add my name onto this petition as well. I purchased P4 from Curious Labs, and was originally very interested in P5, but instantly knew I wouldn't purchase P5 (or use it ... I don't steal software) once I became aware of the "activation" system it uses. This objection is primarily out of concern that the company will eventually not be around anymore (all too common an occurrence in this industry) and my software will thereafter become useless, but also it is because of the annoyance factor ... this is why I don't plan to upgrade to XP either. The very idea of having a limited number of installs on OSes that practically require periodic reinstallation of the entire OS to run properly, even without consider computer hardware upgrades ... well, it seems to me that adding such a scheme to software is much like intentionally building in a time-triggered virus. Also, I have never purchased and never intend to purchase any software that requires a dongle either (I'd have to disconnect other hardware in order to attach it). Nor will I touch software schemes that write strange stuff into corners of your hard drive like Pace ... that's just asking for system trouble, as most anyone with a Pace-infected system can tell you. Serial numbers are just fine by me, though, if CL must have some sort of security device. But they won't see any more of my business with the current security scheme, nor with the hinted-at dongle idea. Too bad for both CL and me, I guess. I'll get by well enough without upgrading Poser ... but will they? As has been said before, the dumbest element of this whole deal is that hackers will undoubtedly find ways around any security device, so those slimeballs who really are stealing Poser won't be hindered much or at all by this security scheme. Instead, it is only legitimate current and/or potential customers whom CL will end up having punished and pushed away. David Sandberg
