i am actually using both windows and Mac version and both do the same thing. It really dont work very well at all on any size files. I am working on one that is 3000 people one with 5600 and my main is 15000 names. system crashes on all three files. when merging info. when trying to pull media library, major bug issues through the program. They wont fix it, they will issues FTM 2011 and get you to purchase a new version before any fixes.
it will let me compact but still crashes.
