Ok so at the risk of sounding very stupid I need some help with Mail please! I've looked through all the settings and help topics but can't seem to fix it myself. Basically whilst in Inbox I double clicked part of the message header and now I can't see message previews in my Inbox! The split screen, where message titles were shown above and then when clicked the body of the message appeared below, is no longer the case. Please someone put my out of my misery as I can't seem to fix it and its bugging me! Thanks for any help.
