I am using Outlook 2003 with Windows XP.

I had a task that shows up on the Today page but not in any other
listing under the Tasks folder. The task also has a subject that is
simply a dash on the Today page. When I click on the subject, it does
nothing. When I try to mark it complete, it does nothing.

After much frustration and troubleshooting, I found that the task was
actually assigned to me from SharePoint. The task appeared with the
original subject in the task list, which is why I couldn't find it. I
was looking for a dash as the subject. I deleted the task in the
Tasks list and the task disappeared from the Today page.

Anyway, just thought I would post this in case anyone else has this
problem.
