Good for you.
Unfortunately they only seem to have tweaked the memory management. If you do a comparison with Reunion my file under that program at idle is taking up 30MB of memory, under FTMM it is 430MB. It then climbs during a session running well over 2GB.
I cannot compact, I cannot export and if I leave the program running too long there isn't enough memory left to exit and I ahve 8GB of memory.
