OK, it didn't go as expected for me either. Exactly the same problem, wallet seems to be in the process of staking but is, even after syncing the blockchain, still completely unresponsive.

Are we the only ones having this problem or are there more people with frozen/unresponsive wallets?

@kakadu: Anything you changed on your pc or wallet that might have caused this or also completely random?

EDIT: After searching, it might have to do with a sudden shut down/crash of the computer while the wallet was open. Still, I'm going to need an answer... anyone?
