The ready-chime for announcing speed games is too slow...
Twice now, I've set up a speed game (2 minutes), set the chime and went off to another page...
Both times after the chime went off, I went to the game and found that the game was now after the start of my second turn!
In both cases, I was the first to play.
But my first turn passed by, as did my opponents first turn, and only then did the chime signal.
