I use Desktop Manager 4.2.2 to sync my 8100 with Yahoo. I've noticed a strange issue with Tasks: when I delete a task on either side, rather than getting synchronized (i.e., if I delete the task on my Blackberry, then the next sync will add the task from Yahoo rather than delete it from Yahoo. Similarly, if I delete on Yahoo, the next sync will add the task from the Blackberry rather than delete it.)

I've tried setting the status to "Completed" but that didn't help. I've also tried playing with settings for All Tasks vs Pending Tasks, but that didn't change this behavior.

Is this a known issue? I did a search but didn't find anything.

I just tried synchronizing Tasks with Outlook 2000 and I get the same issue.
