Add me to the list of those with this problem. On the screen with blank results, I can enter the name that was the object of the search (as I assume the others can), but that sort of defeats the purpose of the feature.
Another, related question: Are Family Search and RootsWeb the only 2 sites that can be accessed by use of the Web button? I've only been using TMG for a few months, but I thought that with V.6 more than 2 sites were shown.
