My Games - which order ?

Could someone please help/assist in the order that my games appears.
I prefer that the oldest games are at the bottom of the list, BUT, for some reason, EVERY time I go into this list, the order changes and I end up with the oldest games at the top. I keep turning the funny little arrow upside down to achieve what I want, but lo, next time I go in, the list is the wrong way round.
(the arrow being at the top left of the my games list)

There is a bug here.

Someone requested that the last column sorted and the sort order is remembered between sessions, but there appears to be a problem with the order that I am yet to resolve. I will work on it this evening, because it drives me nuts too.
