How do you lock the NXT 1.9.2 client? I want to make sure I wrote down my passphrase correctly before I fund it. I can't find a way to lock it to prompt the passphrase entry....Thanks!
Do you mean you don't know how to log out of the NXT 1.9.2 client?
You log out by clicking the icon at the top right of the wallet above where it says NRS Version 1.9.2 in this screenshot.
After you have logged out it will prompt for pass phrase entry.
After you are sure you have your pass phrase saved correctly you can fund it and see how many free Ardor coins you are getting for your nxt coins for the three months of snapshots.
