I first instlled the editor and it worked fine (local host and on my domain).  I have been busy on other things until now.  Now, when I try to use the editor, nothing works.  The editor shows up OK, and the button help messages show up when you put the cursor over them, but you cannot click on anything or get an insertion bar.  Buttons also to not change color when hovered. Cursor stays as a pointer over the text area.  It is as if mouse clicks are disallowed.  What can be the problem?
