No probs with links to private sellers' other items, but the equivalent 'visit sellers shop' on all the business sellers' site that I have tried won't work--the pages start to load normally, then immediately go grey. The backgrounds remain visible, but the pages are otherwise completely unresponsive. Clearing the cache etc. has no effect.
I suspect this is an issue with Chrome OS after the recent update. I'd be obliged if anyone can shed any light.
