Like source code in this post: http://sheenspace.wordpress.com/2010/09/21/callback_functor_delegate_event/
When I first edit the post, insert code into [sourcecode] section for the first time, it was fine. All spaces are their. But after post, and come back to edit again, all spaces are gone. And code is ugly. When I restore spaces and update post, it is fine again. But messed up again after I go back to edit.
What shall I do now? It drives me crazy.
