I hate ads. I hate Flash ads. AdMuncher (www.admuncher.com) has some issues with Vista/UAC/whatever.
Symptoms - IE won't display pages when Ad Muncher is running.
How to make it work: (assumes Ad Muncher loads at startup)
1. Install Live Messenger Beta 8.1
2. Login to Live Messenger
3. Then open IE and doe what you want. Works until you reboot.
