I agree with all your complaints--I have tried and tried to do several genealogy reports and they won't complete. I wish I could revert back to 2010--I did not have problems doing reports of ANY kind, ANY length.
I have other issues with 2012, too, the most obnoxious of which is that I can't call my database up up after exporting to outside media. I had to download my ancestry tree, convert to 2006 and then access it in 2006 format.
It appears that 2012 is an attempt to box users into using the online tree--which I also use, but when you can't even move your own database to a removable media and work on it on a laptop in the library, it's ridiculous!
Sometimes adding frills and graphics causes loss of basic software capabilities.
