I believe there's some issues with the most recent release (1.1.1.3) and WP 3.3.2. It will render the text editor unusable - you can only see the upload and shortcode buttons - the rest is rendered unusable. You can type in the text editor but cannot actually see what you're typing. Really odd - I confirmed the connection between this behavior and Shortcode Pro by simple activating/deactivating of plugins.
