I just recently started having this issue a few weeks ago. I use the default mail app for my yahoo mail, and just added my hotmail account to the list. now all of a sudden I can't load emails! They'll load and you have about 15 seconds to read the email, then all of a sudden the screen goes white and nothing is there now. I deleted the hotmail account hoping that would work, but it didn't help at all. no idea what's going on or why this started.
