If you look at kronolith/js/src/views.js, you'll see that there is a  
cache in the ShowView function. We need to invalidate it when the  
selected calendars change. Can you please create a ticket on  
bugs.horde.org to track this? If that's a good enough explanation for  
you to dig into it, a patch would be even better.
