<p class="MsoNormal"><span lang="EN-GB" style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">You cannot add further listeners to the onRollOver event. So if you later assign myObject.onRollOver = anotherFunction() you over write the orginal
one yes.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-GB" style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">rootIcon.onKeyPress is an attempt to work around that because it can persist and you can use flags etc to work out what to do. The actual events
are onKeyDown and onKeyUp which you can listen for on individual icons, rather than rootIcon.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB" style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D"><br>
