Tiggulok:Could the program be tweaked to take the same balls out of our inventory instead of always defaulting to the starter balls
It already does this, tigger. You just have to make sure you have enough of the same ball in your bag. You can buy balls during a round but they won't be used unless they're exactly the same as the ones you're using, color included.
Play around with the contrast/brightness controls on your monitor. I use a laptop so it's just a matter of tilting the screen for me but you should be able to enhance your view this way. It may also solve the vision problem. GL
