:) I would not recommend IE too for the staff client. But if you change code
related to IE, it still would be an idea to test it somehow?

Yes, you are right (of course). As a purist, you could perhaps say that it
should be even better to refer to window.event. 
With Google, I came across this example for a cross-browser solution:

element.onclick = doSomething;
function doSomething(e) {
    if (!e) var e = window.event;
    // e gives access to the event in all browsers
}
