Possible instability of FastICA with all default settings

Hi,

The FastICA seems to produce different results on repeated runs with the same input data. Here is a simple example:

Input:

X1 X2 X3
1  1  1
2  3  2
3  1  3
2  3  4
1  1  5

Experiment:

<operator name="Root" class="Process" expanded="yes">
    <operator name="ExampleSource" class="ExampleSource">
        <parameter key="attributes" value="H:\ICA\dummy.aml"/>
    </operator>
    <operator name="FastICA" class="FastICA">
    </operator>
</operator>


Repeated runs of this experiment output completely different results in the log.

Are there any tricks regarding the ICA settings that would make the results reproducible?
