Whenever I try to attach an attachment to an e-mail, as soon as I click on "Insert", I get a message saying "this tab has been recovered - there is a problem with the webpage" and I am back with the draft e-mail and no option to select an attachment. If I do this 3 times it tells me it is stopping working altogether. What is causing this and how can I get back the ability to add attachments to e-mails?
