I like IE7, but every time I quit it it pesters me with a dialogue that asks me if I want to re-open all tabs the next time it is started.

I tried ticking the "Don't show me this dialog again" option but that UNTICKED the option above it about re-opening all tabs on next startup! And, sure enough, next startup only the home page was opened!#@#!@#!@

My intuitiveness continues to differ from Microsoft's assumed intuition.
Can someone tell me how to have IE7 automatically re-open all tabs on next startup without having to tick the checkbox every time I exit it?

Thanks.
