Adrian, I agree, this is very odd. It is also compounded by the problem that in firefox the pdf opens as part of the page, but on my pc in Chrome the pdf opens separately in acrobat reader (I obviously have a plug-in in chrome).

However, the glitch occurs on all pages, not just products.

I did note that chrome (in spite of the glitch) opens significantly faster than firefox on any page. I suspect your extremely large inventory that makes up your menu is processed one line at a time by firefox, and chrome is processing the menu in the background whilst the page loads which at some point results in the glitch (all this is a guess I am sorry).

I have marked your post for attention by incomedia in case there is something they know that I don't.

Thanks for verifying. Not a huge problem, but when transitioning from product page to product page it looks way better when the images are in the same spot rather than jumping.  The PDF loading is another issue that I am going to post a new discussion for.
