Chris, it not about whether or not CL's will be a hassle or not, it's one more company that requires an over the top activation method. It's copy protection squared when all of them go that route. I know about Win2K but for the $50 US addon price to a new system it is worth keeping XP and an operating system my users all know and work well with. If it was more expensive to add on the OS I would consider it. And there are copy protection schemes out there that do as good a job (mind you, none is perfect and all can be cracked, including this one, regardless of how many scientists worked on it) but don't cause the user the grief involved with Activation codes that work off of hardware based items. If the activation code worked off of something that followed the user it would work, but hardware is too transient to be useful. JDexter
