I am using Vista Home Premium with SP2, 4 mb Ram, FTM 2012, build 452. I have 4000 persons, 262 media items and 105 MB file size. Have not had any problems with 2012 until now. Am trying to create a small book for teaching purposes. I have named a book, created a table of contents and generated a descendancy report (4 generations) for inclusion. When I try to add anything else, FTM crashes with the two fold message that (1) FTM has to close and (2)search internet for a solution. When I try the search for an internet solution, FTM automatically closes. I have cleared my cache, rebooted twice, compacted my file twice to 0%. Nothing seems to work. This is my first attempt at book publishing, hopefully someone out there has more expertise than I, and can solve my problem. Jerry
