Version: 0.9.1 (using 4.1.4 (KDE 4.1.4), Kubuntu packages) OS: Linux (i686) release 2.6.27-11-generic When you split lessons in sub-lessons, the statistics are only shown for the lowest level. Higher level lessons don't have statistics. It would be very helpful if the statistics would be "summed up" and shown for every level of the lessons.
Has been fixed in Version 0.9.2
