My sync issues since the wonderful "update" have been mainly an annoying pop-up window asking me to unlink my tree when I try to sync. I would just close the FTM program, reboot it, and it would sync normally. I finally figured out that it was only happening after my computer had gone into hibernate mode from being idle too long.

Then today, I started having the issues with freezing and seizing while syncing -- geez, I wish I had never agreed to that wonderful update. I've been backing up up regularly just in case, but mainly use the on-line tree now.
