Hello all I have a strange, very annoying problem with Mail Display on my MacBook Air. I was away for a fortnight up in the Kimberleys, resolutely out of touch of Mail, my iPhone 5 and the net. When I returned I found the problem. I have searched through all the menus I can find, but I can't see how to fix it. As well, I have an earlier model iMac with an earlier version Mail that works perfectly well. The MacAir has Mail 6.3 and the iMac has 4.6. I have updated all the software on both machines.
On the iMac, Mail display defaults to a split window which shows messages at the top and the content of a selected message at the bottom. There is a bar between the two which can be moved up and down to alter the ratios. Double clicking a message displays it in the current full Mail window. That used to be the situation on the MacAir, but now there is no split window. It shows just the list of messages. To view any of the message apart from the subject I have to double click it. This is very time wasting because I can't go through the numerous mails which come in each day and quickly delete those I want to get rid of. I have to actually open them to decide whether they go into Trash. Is this the result of the latest version of Mail on Mountain Lion? Surely not! What have I done inadvertently to create this mess? What can I do to fix it and got back to a split screen for message Display.
