Hi Jamie
You are a genius! I took your tip, installed Firebug 1.11.4 on my Firefox 17.0. When I got to the forum screen with the Marginalia annotations, I turned on the Firebug console with F12 and clicked on the Error tab. Sure enough something showed up:
TypeError: margin.mouseleave is not a function.
Hmm....! mouseleave? I know mouseover, but mouseleave? So I Googled around.
Apparantly, according to http://help.dottoro.com/ljewsllu.php,
mouseleave() works only on Internet Explorer!
But I am using Chrome. Which kinda explains the problems.
I then decided to prototype/experiment my way out of this problem and proceeded to change line 189 of
file MoodleMarginalia.js from:
margin.mouseleave( function() { margin.removeClass( 'hover' ); } );
to
margin.mouseout( function() { margin.removeClass( 'hover' ); } );
Eureka. it works. Now both the HTMLeditor and File Manager load properly.
Thanks!
