This problem just started this morning - worked fine yesterday. Running Win 8 with FTM 2012.
Normally when you have possible matches in the Web Search pane, one is highlighted and you can merge. Now I cannot highlight and the merge button is greyed out.
I can double click on a match and it will go to the appropriate Ancestry web page, but again, cannot merge.
(Update) just went to my Win 7 machine with a different database and it experienced the same problem.
Any thoughts? Steve Reed
