Selecting a range of messages fails unter special conditions: * Open folder, do not open any messages. Message view is empty, though message A is highlighted. * Use the arrow keys to navigate to message B. This is supposed to be first message in range. Do *not* open it, e.g. do not click it or press space. * Hold "shift" key and klick on message C. I would expect all messages between and including messages B and C to be selected. In facted messages between and including messages A and C are selected.
