I can't believe I have to ask this question. I go into the proxy options, and where it says "do not use proxy server for addresses beginning with", I put in "10." And it still tries to go to the proxy server. I have "do not use proxy server for local addresses" checked, and it still tries to go to the proxy server. WTF?!?!

Not sure about Netscape for this, but IE needs 10.*.*.* entered if you want to ignore the 10.x.x.x subnet. I still have no clue what "Do not use proxy server for local addresses" actually does though.
