[Greasemonkey] Re: Memory Leaks

[Andre]

Hi,

you are right. I add several event listeners for a newly created button. 
It is a div with:

     var trigger = document.createElement("div");
     trigger.addEventListener("mouseover", eh_onmouseover, false);
     trigger.addEventListener("mouseout", eh_onmouseout, false);
     trigger.addEventListener("click", eh_onclick, false);

How would I remove them? The refresh is done by the page, not by my code.
