Hi Rebecca,
We are aware of this limitation in the new version (right now there isn’t a way to keep the full resolution) and it’s of a high priority to resolve it. It will be fixed in an update soon, and you can track our progress here.
Also, just to make sure you’re aware, in the meantime you can still use our older version of Ribbet which has the full resolution capability. It’s now available as a program from ribbet.com/download. It’s identical to the previous (Flash) version, has all the same functionality and will continue to work indefinitely into the future. Once installed it will add a Ribbet icon to your Windows desktop / Mac icon dock – you can launch Ribbet from that (no need to return to our website). You can also sign into it with your existing Ribbet account.
Let us know if you have any further questions!
– Ben
