Yesterday there were dozens of complaints in the Google Web Search Help forum on how the Google search box was covered by a blue bar.
As you can see, it covered about half the search box:
The glitch only happened on certain browsers and it was only an issue for about 30 hours or so.
This morning, one of the people effected by the bug said the issue is now resolved.
Googler, Sarah said:
Thanks all for letting us know about your search box being covered--and providing a screen shot. We are working on it!
Do you still see that blue bar in the way?
