Uncaught SecurityError: Blocked a frame with origin "http://102262330009.comet.studio.sketchpad.cc" from accessing a frame with origin "http://studio.sketchpad.cc". The frame requesting access set "document.domain" to "studio.sketchpad.cc", the frame being accessed set it to "sketchpad.cc". Both must set "document.domain" to the same value to allow access.
I created an account for nothing. Please fix it!
Also, could you please explain more clearly what doesn't work in free sketches? Maybe coach marks when you start trying to use /* @pjs preload="http://"; */
