I agree the load time is long. Don't really understand that. Maybe it's the size of the tree...mine's 6800 people. Would be smart to let me get started, then load memory in the background.
And you're also right. I moved from 2006, and I think the report function in 2012 is a definite step backward. I liked the all-in-one and it's gone totally. And I like very much the tree format on ancestry.com - could that same format be included in FTM? The hand drag is pretty standard, so it's always a pain to use the arrows or side sliders. And, like you said, changing one parameter (like the number of generations one at a time) and having to wait to re-gen the entire report is just silly.
Overall, though, I was really reluctant to change from 2006, but I'm glad I did. I haven't uploaded my tree yet, though, and don't think I will. A lot of people on here have a lot of problems and most revolve around syncing or talking to ancestry.com.
Still, great program. Of course, I'm only late 50's, so I have 10 years longer than you to spend waiting on boot-up. :)
