Column-main div relocating on page load

[buddhistwhatson 0]

Hi; When several of the pages on our site load, the content in the Column-main div seems to take one position and then move to another position. It is noticeable because there is some javascript on the page, however, it would be great if that didnt happen. I used firebug, but i cant see what would be making it move. I'm not sure it is the css or the column-main div either. To repeat - the content in the main content area seems to appear and move during loading. Please look to the top of the content area below the nav bar. The page is www dot buddhistwhatson dot com/classes. Would appreciate your help. Thanks

I refreshed your website several times to watch it load, but I don't see any relocation anywhere. Can you try deactivating any plugins to see if the problem persists?

Thanks; I disabled all the plugins and re-enabled one by one (for this page) and it was the amazon affiliate search box widget. I can use the amazon carousel without delay, but the others seem to load very slowly. thanks
