Not a biggy but thought someone would want to know.
If you go to "my performance", select any opponent, and click on the link at the end, i.e. the number that is the total number of games you have had with that opponent, it brings up a list of all the games you two have played. Good so far. However, the little result indicator in brackets always shows the player on the left as having won regardless of the actual result.
And I thought I had more interesting things to worry about!
