hmmmm, I have exactly the same problems as the last post. I called FTM and the gal said our developers' are working on the problem. Well, its been almost 48 hours and still can't merge individuals....except for the first individual I bring up when I boot up FTM...and then nothing. the merge area is greyed out. The public member trees, I think, work.
have been a member for 10 years now and if not fixed soon will let my membership expire and hopefully find something else.
