Hello Aaron, it is most likely a plugin conflict.
What you will need to do is test for plugin conflicts by disabling all plugins and then activate Gravity Forms and test it with captcha. Then activate each of your other plugins one by one until you the issue starts happening again.
You are running this on WordPress 3.0's nightly builds? Be aware that automatic updates with Gravity Forms don't work with WordPress 3.0 because of a change they made in how plugins are updated. We will be releasing an updated to Gravity Forms that makes automatic updates work when users upgrade to 3.0, however if you are already running 3.0-beta then you will have to install it manually.
