13 jun onwards is that possible to go back to yahoomail classic from yahoomail beta?

Once you have the new Mail Beta you will no longer see a switch-back link to Mail Classic, but I'm slightly visually impaired and found an interesting workaround: lower your screen resolution, and as soon as it's too low for the new mail, you will get a message displayed asking if you want to switch to Mail Classic. Click "yes"...:-)
