Very strange bug with toggleSlide and animate

Very strange bug with toggleSlide and animate

Hi fellow geeks

I am developing on this site at the moment;
http://www.thombler.com/myblocs/v2/

If you click the "gallery" link in the top, you should see a perfectly working slide animation..

However, if you click "about", and then click the "gallery" link, it will begin the animation, but get stuck halfway through, and then refresh the main page.

The strange thing is that it's the same php file that's included on both the home page, and the about page, and the ONLY content is the "HOME" + "Welcome to photonlabs." texts.

So my only speculations is that the URL is guilty, and that just seems impossible, and unseemingly stupid..

I have been hassling with this for allmost a week now, and i will need to spend a serious period of time on a mental institution if i don't find a solution soon ;-)

I use jquery-1.3.2, livequery, color, lightbox and the UI expansion

This is the very simple code i use for the animation,

   $('#gallery_a').click(function () {

      $('#subHeader').slideToggle('slow');
      
      a = document.getElementById('gallery_a');
      
      if (open == true) {
         
         a.innerHTML='gallery';
         a.style.color='#FFF';
         
         open = false;
         
      } else {
         
         a.innerHTML='close';
         a.style.color='#FF0000';
         
         open = true;
      }
      
   });


...and the rest is in my index file, so if you need to see it, you can view the source on my site.

Any help will be preciously accepted.

Thanks in advance for spending time on reading this!
