I have the following sessions:
20091229
20100105
20100108
20100109
20100112

In the Observation Database I select File → Print. The Printing script is Default and the Task is Session and Observation data. When I print this out, I get all the data but it is not in order.

20100109
20100108
20100105
20091229
20100112

Finally, attachments are not being printed.

Fixed. Sessions and observations are always ordered by date/time. Attachments (images) will now be printed.
