>I seem to be having difficulty in moving back to a previous form when useing {thisform.hide do form y } in a click prompt button ( which moves fine into form y, but when i issue a unload statement ... {thisform.release show.x} i get an error (Object x is not found)... debug shows

Another approach would be to pass a reference to form x to the init of form y. Keep the reference to form x in a property on form y and then in the destroy of form y, use the reference to set focus to the previous, then null out the reference on form y so that form y can release properly

FirstForm.cmdGoSecondForm.Click()
=CREATEOBJECT("SecondForm",thisform)

SecondForm.Init()
LPARAMETERS toFirstForm
toFirstForm.Hide()
this.oFirstForm = toFirstForm


.....

PROC SecondForm.cmdOk.Click()

LOCAL loFirstForm
loFirstForm = thisform.oFirstForm

thisform.oFirstForm = .NULL.
loFirstForm.Show()
thisform.Release()

If the Show doesnt work, try:

ACTIVATE WINDOW (loFirstForm.Name)
