[Zope] (Win98) Working offline ...

I recently installed Zope on my home machine (running Win98 rather than Linux to appease my partner) which has a modem connection (dial-up adaptor) to my ISP but no network card. If I start the ZServer while working online, it correctly globs my dynamic IP. However, started offline it runs as localhost on IP 127.0.0.1 Starting Internet explorer and pointing to http://127.0.0.1, IE complains that it can't reach this URL while working offline. Is there anyway around this "problem" or do I need to install a network card simply to handle the loopback? I really would like to develop for Zope at home without starting a needless internet connection. Any advice is much appreciated. Cheers, Darran.
