Obsolete. Use SummaryPageDesktop instead (this a a reversed version of this property).
Indicates whether this Summary Page type Script should be hidden in the page list on the form to which it applies.
This may be desirable if the Summary Page is to appear elsewhere on the form, e.g. an Account Status Summary page has its own slot on the Status page of the Account form therefore you probably don't want it showing in the page list.
