a long time we didn't discuss.

I got a problem with your simulation when launched in this page
with Firefox and Chrome but not with IE 7.

Whereas when I ask for it in this page
or in this one
there is no problem ...

When I ask for java console to tell me what's wrong, it close without letting me copy the log so I made a screen capture you can find here

And for the page where it work, I got a lot of error messages you can read here

FF, Chrome and java have all been updated, I have suppressed the historic and cache ...

And now I don't know what to do.

Do you have any idea ?

Thanks in advance,
best regards,
