Refreshing page can cause the user to become logged out
When you log in and click the 'Save Login' button, an item should get created in the browser's localStorage that contains a hash of your key that can be used to automatically log you in.
If you've done this through condenser, then your browser has that key in storage already and this problem doesn't exist. If you've only ever logged into the wallet, the key is not saved, and refreshing the page causes you to become logged out.
