Chrome Slow Down – Any Ideas?

Whenever I have clicked on the little comments and likes icon in the top right corner of my blog screens, it has loaded almost immediately. In Internet Explorer, it still does. In Chrome, it just hangs forever with a little, rotating timer in the centre of the popup.

I have cleared the cache and I have re-booted. It still hangs in Chrome and returns almost instantly in IE. I have also tried it in Mozilla Firefox: the comments and likes load instantly.

Does anyone have any ideas as to what is wrong with my Chrome and how I may fix it?
