In the Mountain Lion version of OSX, reading mail was a breeze. In the messages column group, simply pressing VO-J jumped to the message content, saying jump to text, and you could read the text of the message with the cursor keys. To jup back to the message column pressing VO-J went back, as did pressing backspace to delete the message and jump to the message column group. Now , the behavior is totally different. When I press VO-J, as it did before it says "jump to text" but it doesn't work. Sometimes it says it is interacting with embedded items, but pushing cursor up or down simply reads the message list and not the text of the message.
Anyone experiencing this?
