Bug when adding items to wishlists?

Often - though not always - when I first go to add a product to one of my wishlists, I find the site doesn't display properly after I've clicked the "add to wishlist" button on the product page. If I then hit 'back' and try again, though, it almost always works fine.

For reference, I'm using Chrome. I'll try to screenshot it next time it happens, if you like? :)

Same for me with Opera

Here's a whole-of-page screenshot for you

The same happens to me on Chrome and it always works if I go back and click on the link again. I think it may be to do with the website more than the browser.

I believe so, yes, but it's always useful to report such things when reporting bugs :)
