Which is unimpressive on the whole.

I don't really know if this is a correct conclusion (I'd have to do
some testing that I don't feel for right now), but to me it seems like
the error handler doesn't trigger from an event trampoline. That, I
would say, is probably because the events are originating from COM
objects instead of from the JScript engine.

It does, but not as perfectly as we'd want it.

No surprise - Mozilla catches everything at the window level. Iew
doesn't, it catches the MouseEvents and KeyEvents on document level.

I would be very surprised.
