Gurney,

Lead in your hat will also keep Superman from seeing the kryptonite you've had implanted in your brain!

Sometimes if you don't have a connection but you recently visited the page while online the computer will load the cached page (if you visit your cookies page there are a lot of temp files in there composed of all of the little bits that go into putting the page on the screen). Only when you try to visit something new that wasn't previously loaded do you encounter the information that the page isn't available, etc. If you want to test the system to be sure, go back to the loaded page and click "reload" and it will come back with the message that the page isn't available.

This doesn't help solve your problem, but it might help you see why you seem to get mixed results when browsing.
