[msh441]

I remember having issues with multiple computers and ActiveSync in the early days, but fortunately haven't experienced any of those issues since my last device (Samsungi760) and newer Vista Mobile Device Center on the laptop. No issues whatsoever with the TP2.

If you read the article in the microsoft link you posted, it sort of suggestes that the specific issue refrenced only occurrs when syncing between a 64 bit PC and a second PC (32 or 64, doesn't matter) while using Activesync 4.5. Is that consistant with your experience?

I'm running a 32 bit Vista+Mobile Device Center (v.??) at home on my laptop and a 32 bit XP system+ActiveSync 4.5 at work and have had zero issues.

... that is of course dependant on the partnership rules you establish in order to determine what infoamtion take precident between devices and how conflicts are resolved. Have you checked those settings in order to confirm you haven't set them to duplicate entries? Just checking...
