We're introducing a new interface for submitting Earth Bugs at
http://code.google.com/p/earth-issues/

You can submit a bug report, from the "Issues" tab of the above page
or visiting directly at http://code.google.com/p/earth-issues/issues/list

Moving forward, we'll be using the new improved interface that will
display reported bugs in a tabular format. Although we can't reply to
every bug report, you'll receive notifications when your "starred
issues" are updated.

Also, if you think a bug should be renamed or changed in some way
after you've submitted, include that in the bugs comment section. If
you're having issues using this interface, please let us know by
responding to this thread.

If you were involved with a bug report on the old "Found a bug
(especially in 4.3)? Let us know!" Earth Help Group threads; note that
they have been retired. Although we've already looked at previous
reports, please feel free to resubmit them here. We'll compile the
results and make sure that all of your information gets to the right
place.

You can post the KML documentation or support related bugs by visiting
at http://code.google.com/p/kml-samples/issues/list

We appreciate your feedback and help as we work to improve Google
Earth!

Thanks and keep exploring,
The Google Earth Team
