Problem with duplicate.
 

When I try to duplycate serwal ep curves it only duplycates the green marked curve and not the white marked. This is PRETTY enoying. Can any one help me out? (Using Maya 5.0)

That's odd... It should work. Did you reset the duplicate options? Also do you have the 5.0.1 patch?

check where the axis for each curve is at, maybe they are being duplucated right on top of each other and you can't see them. (look inside the hypergraph and see if they are duplicated there)
