Rather than 'not working' I would suggest it might just be system slowness. I'm seeing more than the usual delay today in getting translations scored and when I ask for more translations to rate, again, quite a long delay.

No, it's not system slowness - if I right-click and "Open in new tab" they load straight away. It is happening on most of the site; eg. if I click the "Home" link at the top of this page nothing happens, the "Continue" button at the end of today's lesson didn't work, and numerous others. I'm using Google Chrome 21 - I'm thinking it might be an issue with the browser.

Where is this happening?

I think I might have solved it. Have just uninstalled a browser add-on called Infoatoms. Links seem to be working again now.

@Veish Sorry then, for re-interpreting your comment. Seems I wrongly assumed what you were experiencing was similar to me.

No problem. It was my fault for not checking my system before blaming the website.
