Hello Everyone. I have a problematic wallet contracted that I created using Mist. The wallet is showing a positive balance inside Mist, and on Etherchain and Etherscan. When I try send funds from this wallet address to any other I get an error that says "Unknown Account". I know the password is correct. Interestingly, whenver I search for this wallet on Etherchain/Ethercan I can see the address and the balance, but then the browser tab completely locks up. I've tried everything I can think of. Has anyone else heard of this problem? Do you have any suggestions?
