Anybody else seeing this?
Not generally.
Can you describe the setup more? Where is the folder you're syncing to? Where are the files stored before syncing? What options do you have enabled in the Handheld settings? How is the sync list generated? Without more details, it is very difficult to assist. Totally guessing here, but to make sure you are aware, if Resync if Date Modified has changed is enabled, you will often get files resyncing. Date Modified can change for a wide variety of things, including tagging changes.
