I HotSync about 3 times a day. Somedays the 650 and ACT! sync flawlessly; other times, it will create duplicate contacts. I have 2,511 contacts... I abort the sync after dupping about 10.

What am I doing wrong to create all these duplicates?

I use the conduet Companionlink. Their customer service has been great but they can only suggest that I do a "Purge and Reload" each time. Defeats the purpose of "syncrinization..."
