Many of my forms are opened by buttons from several main forms.  When these
forms open they often select records based on information displayed on the
main forms.  Sometimes calculations are performed as well.  

Many times it seems that the forms do not open cleanly, i.e. parts of the
previous form show through until the form opens in maximized view.

Is it best to put DoCmd.Maximize before the selections of records and
calculations or after.

Any other recommendations for a clean display of forms is appreciated.

Thanks.
