Thanks. It's working now. I don't know why, but in case someone else has a similar problem, here's what I did.
- I did a fresh boot on my PC.
- I did a sync.
- During the sync, I noticed that I was not syncing tasks, so I put a checkmark in tasks and it synchronized them as well.
- I disconnected.
- I reconnected.
It works fine now.
ActiveSync is the strangest animal. How I long for the days of the PalmDesktop. ;)
