I agree with several posters on this forum - the user should NOT have to downgrade Internet Explorer to get FTM to work. End Users are NOT responsible for fixing vendor supported software - band-aide be darned! I do understand that the Microsoft Update that occurred on 4-19-2013 could have caught the FTM Development Team by surprise - it happen all the time - software development/maintenance is a Bear.. However, this is a MAJOR issue for a large number of FTM users and FTM/Ancestry should have immediately posted INFORMATION on their main WEBSITE- "We are aware of the Problem and are working diligently to resolve the issue".. Also, it does not take an IT Professional to come to the conclusion that the problem is related to IE 10 - just read the evidence in this forum. This is inexcusable!
jnye042 - interesting information - were you actually referring to Internet Explorer V8 vs V10 ? (rather than "Windows")
