Guest: MS Vista, clean with only one program installed, a poker client
I've been using Parallels for quite a while, but wanted to try out VB because, well, I don't have to convince users here why I would want to do that

With VB, the problem I have is much worse - Vista loses the internet connection every 4-8 minutes. I saw elsewhere in the forums here that changing the networking from NAT to HOST solved a similar issue, so I tried that to no avail.
I'm unsure where to look at this point now. Is it a VB issue, a Vista issue or a Mac OS X issue?
Thoughts?
