[jQuery] [validation] my page disappear when data is filled into input


The strangest thing is happening to me... and I can't firgure out
where it comes from !
I'm new with the Jquery framework and more expecially with the
validation plugin.
I've created this page: http://dev.sonycenter.be/fr/
If you go at the bottom right corner of the page, you'll have the
newsletter subscribtion form... try to type in a e-mail adress, as
soon as you type one character after the "." (following the domain)
the page hides (but if you click view source (and scroll down) you can
see that it is there...so the page has not been refreshed or what so
ever....)
How can i prevent this ?
thanks for your help !
