Opening "tasks" in Outlook 2007 hangs program

[harrie.barron]

I use Office 2007 with Vista.. It worked OK until today when I synched
with a Windows Mobile 5 device (that had old data..) Now I am stuck,
each time I open Tasks, Outlook hangs. When I open Task Manager,
Outlook's status is "Running" and it is using 50% of the CPU. When I
End Outlook and reopen, it starts OK (after verifying the data..) and
email works.. until I reopen tasks!

Can anyone help?

Thanks,

Harrie
