Let me clarify what you did - specific commands at this time:

You have 3 forms: FORM1, FORM2, FORM3

Form1 :
Commandbutton1.Click Event: 
DO FORM FORM2
THISFORM.VISIBLE = .F.
Commandbutton2.Click Event: 
RELEASE THISFORM

Form2 :
Commandbutton1.Click Event:
DO FORM FORM3
THISFORM.VISIBLE = .F.
Commandbutton2.Click Event:
DO FORM FORM1
RELEASE THISFORM

Form3:
Commandbutton1.Click Event:
DO FORM FORM2
RELEASE THISFORM


Is that what you exactly did?
