I did a fresh sync this morning after updating my ACT! task list for today (moved things to different days, erased some tasks), and after the sync in DejaOffice I have tasks on today's list that I erased showing up, tasks back on today that I moved to other days this week and duplicated tasks for today.

You can see my software versions, etc., in my signature. My CL Express settings include Data Types set to "Sync Both Ways" between ACT! and my Bionic. I'm not syncing to the Andriod native contacts or calendar.

Anyone have any troubleshooting ideas?
