Making a form work in calendar view
 

I have a new form set up which forces a field to be completed when an
appointment is made. However, if you dont double click on the calender (to
open the form) but just click on the time you want the appointment to be and
do a quick entry, you get a message 'a field on this form requires a value'
and then the entry disappears. Is there a way of forcing the form to open
if you do a quick entry this way...?
