After upgrade, the admin page look ugly. It is possible to reset the layout to default?

That is not how it should look like. Here is how: http://www.zenphoto.org/screenshots/zenphoto-1.4.3-admin/admin-overview.jpg.php

Are you sure you did upgrade correctly and the browser cache is not playing tricks and is still using the old css with the newer layout? Such cache fun happens a lot!

Also what browser is it? Ir does work for us, otherwise we would not have released it and you are the first to complain so far.

acrylian, clear the browser cache fix the issue. Thanks!
