Browser hang in Google Chrome 15

I’m able to consistently cause Google Chrome to hang by attempting to create a new LingQ. I click on the item marked in blue and the cross and tick appear, I then click on it again and it causes two lots of crosses and ticks to appear. The whole tab in chrome then hangs with a hung script error. I then need to reload the entire page.

This doesn’t happen in Firefox. Happy to send screenshots if this hasn’t been reported before.

I just tried this and didn’t have any issues with it. Sometimes the page can hang when marking words as Known or Ignore, especially in longer texts, but this seems to be a fairly rare occurrence.
It would be great if you could send some screenshots to support (at) lingq (dot) com so we can take a closer look at this issue.
