Yeah, well it's different.

My advice usually to someone using Daz Studio after using Poser.

Is simply to just accept that Daz Studio isn't Poser and isn't trying to be. Things will be a lot of little differences and at first may seem even a little uncomfortable but most are different for a reason and given some time and experimentation will seem just as natural as any other system and some instances better. There is a lot of community support about for DS so don't be afraid to ask if you get stuck with something. :)
