The collision does not work when using SteadyClock (or ImpulseClock with Timer)

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Open Blizzard example 
2. Add:
addInitializer(new CollisionRadius(20));
addAction(new Collide());

to RainEmitter.as
3. Compile and run - the particles are being generated and then stop immediately

What is the expected output? What do you see instead?
The particles must run and collide


What version of the product are you using? On what operating system?
Stardust 1.3.186

The same is when using Impulse Clock and running clock.impulse() - in Timer. 
Most particles stop after every second call.


Please provide any additional information below.
