The update frequency setting has a default value of 60 minutes. When I change it (tried 5 and 10 minutes), the change doesn't persist when I restart the program. Also, the last update time that is displayed is usually over an hour even after the setting is changed.
Using newest version 3.4.6.
@hberry - That might be intentional. You didn't say what weather source. If you are using one without a private key, it is limited to once an hour. Weather sources with private keys can update more frquently.
