"Design This Form" strange behaviour and not displaying as it should
 

Recently and only affecting the contact form, when I choose "Design This
Form" or "Choose Form", on opening the form in design mode and without me
performing any action the form appears wrongly.
What primarily happens is the note, contacts, and categories fields on the
bottom of the General Page shrink and move up independently of rest of the
fields on the page.
This is alarming and disconcerting and damn right frustrating as I have to
correctly size and place these fields as they should have been and were
before the problem started . The strange thing is that if I run or save the
form as an .oft without any editing, it displays as a normal contact form
would and the phone number edit dialogue boxes work leaving me to deduce
that no customisation has taken place on the General Page.
Can anyone explain how I can correct this behaviour and get an unchanged
form when I open a contact form for designing.
I had previously posted this on the
microsoft.public.office.developer.outlook.forms unfortunately; I have had no
answers to this so any help would be greatly appreciated.
Thank you,
James
