24hrs from when they enter your wallet, if it's unlocked.
i have them 48 hours and wallet is unlocked all the time and still no stake
If you have no problem in sending and receiving coins, then your wallet is working.
Try this,
Settings / Encrypt Wallet,
Once you set Pass phrase and restart,
you will see the "Unlock Wallet" button located the bottom activated.
Click this button once, then it will change to "Lock wallet".
Then wait another day or so.
I did that the first day i started the client(4 days ago).
hmm.. Try restart your computer one more time if you don't mind.
I began to receive my PoS after about 4-5 days later, and it is quite random. It is not always after exact 24 hours. The minimum is 24 hours to start getting PoS. I guess the Dev needs to explain this process more clearly, and suggest any tip for this kind of 'not getting pos' problems.
Restarted pc and started client will wait for another 24 hours to see what happens
