What GPS receiver are you using ? I have a Delorme Earthmate USB. for it to
work under XP or Vista, you have to install a Serial Emulator. Why MS can't
have Streets work directly USB is another sore spot with me.
Since this question has been asked a couple of time, I though I would test
mine out to know for sure. I loaded the 1.011 version of the software and
even though I got a few, this OS isn't supported, it loaded and appeared to
work. I then check and they have a newer version of the software (1.07) and
it doesn't say Vista compat, but it was released Feb 2 2007. it still
complain about a non supported OS. But It still gets a lock, even faster in
my opinion then the 1.1.
I seldom use my laptop for a GPS anymore, but I can confirm this config
worked, or at lesat worked at a basic level
