The script doesn't work in IE without the first "return true", but you're right, the second one is not needed.
In fact, (just tested this) the script doesn't work either way on Opera 7. Opera has a way of not listening to repressive scripts. For example, you can always resize a new window in Opera, no matter what the javascript says.

Thanks, I wouldn't have known that about Opera, but as browsers evolve to empower the user experience, it's as expected.
