Sigh. Set a breakpoint at the beginning, then single-step with F10 or F11.

Add breakpoints to your listener. There might be some auto-debugging of 
event listener code, but I'd have to check on that.

That's how it works. With Firebug.

I've been doing client-side cross-browser scripting (and authoring) for 
several years now. I'm completely aware of these problems. c.l.js is the 
wrong place to whine about that.
