I have given up on FTM after using various versions for at least 15 years. FTM 2006 (or version 16) is the last one that works for me. The newer versions may work fine for small databases but are extremely slow to the point of being unusable.
Also, don't believe that FTM 16 will work on 32 bit versions of Windows 7 as was advertised...it ain't so.
I am reluctantly moving my database (about 160 MB with 35,000 persons)to RootsMagic 5.
