Horizontal scrolling in Safari on one content type only when logged out? So I have spent numerous hours trying to solve the following issue and without success I bring it to Drupal Answers. For some reason, on my site for content type 'level_1' when browsing in Safari it creates long horizontal scrolling. The strange thing is that when you are logged in, the issue is not there. Furthermore the issue doesn't exist when I coded the HTML/CSS pre-Drupal installation.

It's not an issue of caching as I've made changes and checked they followed through when not logged in.

Anyone have any ideas?

If someone has the opportunity to try and debug this issue it would be greatly appreciated. 

The error occurs here in the Safari browser:

Thanks for your time.
Looking though the markup, the problem is on the H2 for your search form.

&lt;h2 class="element-invisible"&gt;Search form&lt;/h2&gt;

Can't say exactly what's up, but if you take off the width from .level1 h2, .related h2, .tabTog h2 then it seems to be fine.
