"example.com" ruining localhost WAMP development

[eluser]Unknown[/eluser]
Please note that this has nothing to do with deployment, so far as I can find. This simply is killing my WAMP development, because I cannot default "example.com" to "localhost". Can someone tell me how to fix this on my development machine? Example.com is restricted to documentation (this is what it tells me) and in no way functions as a localhost replacement. (CI is the only framework to do this, ever, and I cannot find anything to edit that will fix it.)

My environment is XAMPP 1.7.0 (Apache 2.2.11, PHP 5.2.4), on Windows XP SP3.
