Entering scores moves players around as you're changing their scores
Currently if you're entering a scored game, you can adjust the player's scores by clicking on the up/down control. However, this causes problems because the order of the players is adjusted dynamically by their score. So for example: Player1, Player2, Player3 all play a game. Player1 gets 5 points, player2 7, player3 10. You click the up arrow 5 times on Player1, so far so good. Now you go to Player2. As soon as you click from 5 to 6, making it so that Player2 is ranked first, the controls swap places and now you're changing Player1's score instead. So you need to move the mouse up to Player2 and finish adjusting the score. On to Player3. He starts at the bottom, and as soon as you get to 6 he swaps with Player1 to become second rank, and again as he moves from 7 points to 8.
Obvious solutions: don't reorder dynamically, or don't allow the use of the arrow buttons.
I've definitely experienced the pain of this as well; it's a pretty annoying user experience. I'll make sure this one gets prioritized for the not-too-distant future.
I'll try to wrap this up this week.
