Ah, Thank you very mush. It was a problem associated with ‘Role Scoper’ plug-in. This complicated plug-in assigned users edit capability somehow… By tuning some subtle option, I fixed problem!
Now I can use this lovely AJAX plugin unlimitedly.

Thank you so much!

Ronald Huereca,

Yes. This erroneous edit permission happens to subscriber role users. As you know, subscriber role users cannot post their own post.
They do not have any capability for comments in setting options, but they still can edit whatever they want to.
