Hi there,
I´m new with CiviCRM, so, please forgive me for some "stupid" question...
I´m trying to show a newsletter subscription form.
It happens it´s showing with an unecessary horizontal scrollbar.
Please, go to http://www2.webbusa.com.br/portal/index.php?option=com_civicrm&view=Profiles&Itemid=345&lang=pt to see...
I don´t know where I can find this solution.

I tryed to make another version of the same form with standalone form that I putted the generated code in a article.
http://www2.webbusa.com.br/portal/index.php?option=com_content&view=article&id=123&Itemid=349&lang=pt

The layout is fine, but It seems it have an instable work, because sometimes the submit action sends me to my front page and when I check this subscription (CIVI backend), nothing is changed... Sometimes, the subscription works fine.

Does someone knows what could be happening?

I would appreciate some way to solve this ASAP.

Thanks in advance
Ana
