On the withdraw screen it tells me:
"Available amount to withdraw: 0.42 BTC (41.51 Chips)"
but when I tried to withdraw the available amount, it told me it was an incorrect value.
That's because I didn't really have 42 bitcents - I only had 41.51. So you need to round down, not round to the nearest one.
It let me withdraw 41 bitcents, so that was the problem I guess.
