Draft Email Over Written


New Email
I was sending replying to an email while also havind a draft email open using yahoo mail on Google Chrome. When the email was sent I found that the email I was replying to had overwritten my draft! Is there anyway I can recover my draft mail ?

I had been building up the draft for sometime and has been using it to store information and I could really do with getting it back ..

I tried doing a mailbox restore from 2 hours prior to the incident using this link .. http://help.yahoo.com/l/us/yahoo/mail/yahoomail/mail_restore.html
but I haven't got any email from yahoo administrators or anything so I'm not sure if anything is going to happen. I am reluctant to do it again ...

Anyone have any ideas ?

Thanks in advance
