I think there is a new bug since 1.6.0.0
When I am in a message, open from unified folder, if I swype to the left or right it can't move to the next or previous message. Neither is correct the label on the top with the number of messages (it doesn't show anything).
It only happens when you open the message from unified folder. From a particular account folder it works ok. Label with number of message works correctly ('Message x from y')
In previous versions it works ok too.
