I have problems with curving a shape, I want to make a line that curves but when I do it changes all the lines befor the 1 i want to curve, I allready ask about this problem and the answers where:

-Make certain your selection scope is not set to all frames.
Then, in the frame you want to curve in add a curve to the shape.

-Also, if the shape is a symbol which is the default set in File > Preferences, point changes in one frame instance will affect all. Change the default or on a shape by shape basis, use the Properties popup Is a Symbol property. Symbols result in significant swf file savings but are not appropriate for shape tweening type animations.

I need another solution, I have the demo maybe that is the problem?
