I'm using the Windows wallet. It seems to be working in that I received successfully some xcr from bter. But when I try to send to another account after 1 or 2 confirmations the synchronizing block message flashes in the bottom and then the confirmation for that transaction resets to zero. Then it starts over again getting 1 to 2 confirms and then resetting back to no confirms. Eventually after checking back later in the day or next day the transaction disappears and the xcr are returned as if it never happened. So my received xcr from bter shows up on my windows wallet and checks out with the blockchain explorer. But any sends using windows wallet never go through and never shows in the blockchain explorer.
