you need to unlock the wallet then leave it online.
So.
Unlock and online wallet = pos work
unlock and offline wallet = no pos
Right ?

P.S. thx

Why my wallet stuck in block 4478? Already 3 hours past, anybody has some idea?
Is your wallet version is 1.6.0.0? if not download it first then delete all the files on your sharecoin folder ( in your appdata ) except your wallet data and make a back up of it. Your good to go!
