We rolled out an update fixing few Opera related issues in Zoho Notebook. With this update you'll now be able to use most of the functionality of Zoho Notebook in the latest version of Opera. I am saying most of the functionality because we know there are still some pending issues (like Chat inside Notebook) which still needs some work. This is just a start. We will keep enhancing Opera support.

If you are an Opera user and face any issues, do let us know.
