Vector points issue

Hello everyone,

So my issue is this.  I create a mouth shape with a certain amount of vector points that I will need to animat the mouth for speech.  The problem is, if I maniplualte those points in a fashion that is too 'smooth', Flash decides for me that I don't need certain vector points anymore and removes them, essentially making the two lines I had into one line.  This is driving me crazy.  Is there a way to prevent Flash from doing this and allowing me to maintain the number of vector points that I originally put in place?

Thanks,

Jimmy

PS: I'm using Flash CC pro
