Ok, so I correctly guessed the problem ;o)

Mmmm, I can't do that, as:

1) I would have to create the stylesheets every second (I use them to output 
datas during instrument scans, and I have 5 or 6 different stylesheets, 
used for screen output, and different files formats outputs);

2) I can't cache them, as a new thread is created for each new point of the 
scan (Pyro mecanism).

I have to find another solution, by adding some new methods and propagate 
the new params, without creating a new stylesheet.

Thanks,
