The "all you need to do" bit is exactly the way this has wasted my time. I'm not saying that doing it is particularly complicated, nor that any individual occurrence is especially onerous, and in fact it usually isn't (though you do lose your state, and that's annoying) - but the time taken mounts up!

Ah well. I've said my piece. If your experience hasn't convinced you, like mine convinced me, then I imagine yours was a lot more fun ;)
