[Koha] Nearly installed... one more q.

Hiya I smell it running. (I'm doing it on Windows, remember?) I can now use virtual hosts to bring up the opac and librarian pages,but when I run any script, it returns a blank screen. (For example, when I try to search the database for a book or a user, even though it is empty at the moment) The apache logs show no errors. Any idea what can cause this? I must say this is what happens in Opera. For some reason in Internet Explorer it now tries to establish an internet connection, as if it's searching for a dns that is not local. Don't know what I changed to cause this. Got irc runnig so I'll pop in one night and say hello. Right now gotta crash. Ta Geo
