dooglus, thank you for your input. I can confirm the Withdraw bug (on desktop). Also, I agree about the dialog box suggestions. Also, the Internet drop scenario is a good test case, which I can investigate more later. For now, if your connection drops, you may need to restart the client.
BitCoiner2012, What is happening is that your bet is small enough that even though SD reports a Win, you've lost overall value due to the tx fees. I will bring this up with evoorhees to determine how to best address this confusing behavior.
BitCoiner2012's observation about the Pending behavior is correct - the underlying library (bitcoinj) does not (yet) allow spending unconfirmed transactions. I agree that this behavior can be improved, and have suggested an implementation to the bitcoinj folks. They say a similar fix is in the works.
(Edit: I'm also noticing the flat green background peeking out on the Right and Bottom edges of the Desktop edition screenshots folks have posted. That shouldn't be there. Can others confirm this? It must be platform-dependent, because I have not seen it in my testing. This first version is designed for a fixed resolution, and the window should shrink-wrap itself to the pretty textured background with no edges peeking out.)
I suspected as much, I wish it was clearly listed exact btc amount like we have in other transactions (if I do on blockchain, or in regular wallet, I can see exactly what was sent and received, here I get a balance, etc).
As far as the flat green background, it is escaping the gui on the right and bottom for me Windows 7 64 bit desktop.
