Strange error

[David Aliaga]

Hello all:

Have any of you met this kind of error:

I have a simulation, when I started to run it I stop
it right click on the raster change a value on the
probe, then click on the left button(of the probe) to
make a complete probe with the parent object and
change another value then when press start again it
crashed. 

In the last part there is the backtrace of the error.

By the way it does not happen if I change the values
in the complete probe first.

Actually it is a matter of curiosity because if I keep
the right order no error happen but I would like to
know what do you think about it 

David
