How can I disable the default right-click event in krpano

I have a requirement to measure continuous line lengths or polygon areas on a web browser and end the measurement by right-clicking the mouse when needed. This operation provides a good user experience. However, whenever I right-click, the krpano context menu pops up. Even if I try to prevent it from appearing by monitoring and controlling the DOM interface of the webpage, it still executes. I would like to disable this behavior. Is there a way to achieve that?
