Not that I know of off the top of my head. But you can always remove the "click" listener to the components on the page.
E.g.,
myComponent.removeEventListener(MouseEvent.CLICK, onMouseClickEventDoThis);
It's a pain though, since you would have to do this for every visual component.
What I've done in the past, is just make the component.enable = false. That way, it greys out and doesn't listen to any events.
myComponent.enable = false;
Just remember to re-enable it when you're done with the busy cursor.
myComponent.enable = true;
