Hello hoborg! Just a question: are you using the US Version of Poser4 on a non US operating system? For example on a German system ? If that's the case, look at the comma in the joint parameter values. It have to be a point NOT a comma ! BTW, I rate this as a real bug. The solution is to either set the points manualy in all fields of the joint parameter dialog, or to set the comma to the point representation in your operating system. Dont't know about the Mac's but helps on Microsoft's OSes. Bye, Arthur.
