After completing the "Compact File" operation without error, a pop-up window indicates completion and shows the file reduction %. However, after closing that pop-up window a 2nd pop-up widow appears stating "Family Tree Maker has stopped working", giving the option to either check online and close or simply to close. After it is closed and I then reopen FTM2012, it gives a pop-up stating that it was not closed properly the last time and I may need to compact my file to resolve any issues. But when I do this, I problem I described above repeats. However, if I simply ignore this "Compact File" pop-up request, FTM2012 seems to open my file and operate successfully. I have experienced the above problem for some time now and although FTM2012 has no apparent problem if it is opened at times other than after the "Compact File" operation, I am concerned as to whether there may be some problem with my family tree file.
