Google bugs

I am a Google Reader user. One day, I found a bug of Google Reader on IE. If I label an item as "unread", the item next will be labled as well. I could not believe the Google dev team has missed this. If I had missed such a bug to the release in our team, I would not lose all the bonus. I filed a bug on Google Reader Dev team blog. But nothing happens. No one replies. Nothing fixed of course.
