am unable to send my email because when I click for the cursor to type the security letters in the box, it won't let me. therefore I cannot send the emails.|||Everyone is having the same issue, there has been no solution offered for this, in the meantime you can use one of these links until it gets fixed or disappears, it's basic, no frills, but it works. http://us.m.yahoo.com/p/mail or: http://uk.m.yahoo.com/p/mail or: http://de.m.yahoo.com/p/mail
