Reaction Manager adds a third state, State03,
w ith the state (slider) value at 100.0 and the
Sphere01 / Hemisphere value at 0.750.
Also, if you click Slide01 / value in the Reactions
list, you can see in the graph showing the
slider value on t he horizontal axis and the two
reactions on the vertical axis. The scale between
the two differs greatly, so the Hemisphere
reaction on the right side of the graph looks
like a straight line, but if you click the Sphere01
/ Hemisphere slave entry in the Reactions list,
the graph shows a steady rise from 0.0 to 0.75.

Over the left half of the slider ra nge, the box
