Sorry, I'm not seeing anything that weird...what do you mean by "can't view any messages?" What happens when you double click on them?
Are you referring to the lack of a "preview pane" that shows message content in the bottom portion of the Inbox screen? There should be a "bar" down near the bottom (with a dot on it)...double click it or click and drag the bar to the desired size.
Are you referring to the order of your messages in the Inbox? You've sorted them alphabetically by sender, click on the date heading to sort them by date.
Did I hit on your issue or is it something else I missed?
