I am working on a site in Portuguese and using Google Translate since I don't know Portuguese.
The problem is the annoying popup that appears when hovering over a link in the Admin Menu bar that covers the menu.
I found and posted a solution here http://productforums.google.com/d/msg/chrome/8oA_K-KpcqA/AKjfNu2XU4EJ using the Adblock Plus extension for Chrome with a custom filter that blocks the popup
The custom filter is "##div#goog-gt-tt"
Hope this helps
