The only thing I see wrong with your code is that you are calling oMyObject.Init() twice (once in the CreateObect, and once explicitely with oMyObject.Init())

I suggest you check these three things: 1) Check that you haven't done some sort of RELEASE, CLEAR ALL, etc. 2) Also, check that you haven't called another function with a reference to your object and that that function is not still executing - this will definetly cause a problem. 3) Check that your object has infact been created -- TYPE("oMyObject")="O"

This works for me - (and it's basically the same as you have done) So - the problem is not in the code you've posted.

***Main.Prg
PUBLIC oMyObject

oMyObject = CreateObject("TextBox")
oMyObject.Tag = "Here"

MyForm = CreateObject("MyFormClass") &&will run init and wait window
MyForm.Show()

DEFINE CLASS MyFormClass AS form

DoCreate = .T.
Caption = "Form1"
Name = "Form1"

PROCEDURE Init
WAIT WINDOW oMyObject.Tag
ENDPROC

ENDDEFINE
