I just wanted to say that the Uninstall of McAfee worked for me! I had a brand new Toshiba Satellite notebook that came with Windows Vista Premium installed and Frostwire wouldn't work at all for me with the same symptoms (blocking / locking down / hijacking the Internet connection). Removing McAfee removes the problem!

I put the fix on my Vista Review site so hopefully we can help others.

Also - to anyone that reads this, I'm trying to log a list of software that no longer works in Windows Vista on my forum, so if you know of any other P2P related file sharing software (or any kind of software) that doesn't work in Windows Vista since you upgraded - please let us know!!

Thanks! The more info we collect, the more people we can help get their software working again - or help decide whether or not to make the crazy jump by upgrading to Vista!
