Product detail listing issue

Hi

I am using the Classic Template V1.5.1 & I did not change the product_listing.php.

My product listing detail should show up as
Description
Attributes
Additional images

But sometimes the page shows up in reverse order with attributes first then Additional images then description, example
http://www.simmar.ch/catalog/index.php?main_page=product_info&cPath=81_73&products_id=215

If I refresh the page then product listing detail shows up as normal.

I would appreciate any ideas on where to look. I had this problem just for about a month now; site was running for 6+ months.

Alternatively could I somehow automatically refresh the product listing detail.

Thanks for any help I think this could be the reason my orders fell off dramatically in the last month

Forgot to say I only saw this in the German language version not the English.
I think this means the CSS is OK & maybe means I changed something in a "German" PHP file that caused this?

Did some more experimenting; I see this Chrome but not yet in I.E. :(

I found a solution in this forum to a similar problem that seems to have fixed my problem.

I just added these to the end of my css file
#productPrices+br, #productDetailsList+br { display: none; }
#productAttributes { float: left; }
#productAdditionalImages { clear: both; }
