I have heard that Family Tree Maker is really built on the Microsoft .NET (dot net)
If that is true, and you are having problems, can you check which Microsoft .NET framework is installed on your PC?
The .Net Framework 4 stuff on my PC is dated 1/16/2012.
I also have IE 10 installed but have designated Chrome as my default browser.
I am not seeing any of the problems that have been reported.
