I know how organize my photos by date (oldest first); and program shows pictures well, aggregated by months, increasing values.

BUT, inside one month, pictures shows in decreasing order !!!!! Why ????

Example:

> December 2011

       > 25'th

> January 2012

      > 20'th, 15'th, 9'th <<<<<< ????? (must be 9'th, 15'th and 20'th)
