That doesn't work as it needs the pause to be 500 millisecond so have the desired effect which add a noticeable pause in the character actions.
My work around is to insert the "hide cursor" function in the action in the scene before that calls the scene change. And a condition that makes sure it only triggers at the appropriate time. This works perfectly, but I do believe this is a bug that is hopefully fixed (and it appears that it already was once).
Thanks
