Oh yes! I (and others to follow) know what the problem is! You have inadvertantly engaged spline interpolation after the blink. When I am inserting a blink, i ususally do this: key at 40 value zero key at 41 value zero key at 44 value .9 or 1 or so key at 47 value zero key at 48 value zero and then make SURE 41-47 are linear interpolation. The extra keys outside the blink are like firewalls to keep the extreme slope of the blink from setting off spline craziness. Do you use the graph? it's realy easy to spot in graph mode. ::::: Opera :::::
