I have an email address from Yahoo. I can receive emails but once I go to send one, when I'm on the page were it asks there email address and subject, but there is no box where I can write my email. It has the subject and their address but below that it has no box to write. But I asked my girlfriend to try it on her computer with my account and everything and on her computer it did have the box to write. What can I do to fix and what's wrong? Thanks
