I am getting "not responding" for several functions within Outlook. I
am running it under Windows Vista Business (32 bit)

When starting Outlook today starts well.

If I then click on Calendar I get the monthly view and can add
appointments etc to it. However if I try to go to a different (daily
or weekly) view or want to access an appointment from the down arrow
on the date (3 appointments) it freezes and eventually get the
message "not responding"

If I try to go into Tasks again I get the message "not responding".

Has anyone any ideas as to how I can get around this?
