Thanks!

Did you notice, that when you have a low balance ("Your balance: 0.00000081 BTC", after some unsuccesfull spins ) and you click "all", I get Bet: 8.1e-7 which gives "invalid bet" when I push "spin"? When I push spin again, it works fine now. However, I'm now at (Your balance: 0.00000020 BTC) where bet-field says "1.9999999", some division error I suspect.

Hope this helps!
