Previewing Public Calendar Appt. creates local Cal. Appt.

[Dan]

Here is a strange problem, I'm wondering if anyone else
has come across. If so how did you resolve?

Open a public calendar, and open a appointment/meeting
that you are not an attendee. Then close the appt. by
either using the File, Exit or the control box 'X'.

Go to your personal calendar, and the appointment is
added there.

I do have Author rights to the public calendar but don't
see why this would matter.
