Quote - Main_Cam set to animating off, set yrot to -90, turn animating on, set yrot to 90, save cam (while animating is still set to on!)
No staticValue line and k value is at 90 (last value entered)

Thanks msg24_7. So in P7, if you don't want to record the staticValue, you turn Animating on. Where as in P6 it is the other way round. Strange, I haven't quite got my head around which way is best, I suppose they must have had a reason for changing it, but it certainly is inconvenient to have to have a pose that works differently in different versions. And there is still the question of what exactly is Poser 2010 doing differently from P7 when it applies a cm2? My assumptions have not been working well lately, but I assume that if you save a pose from P7 whilst Animating is turned "On", thus only saving the k values, then 2010 has no choice but to apply that one set of values.
