David, Hi again!

I has your ObjRef App.
I call it in QueryUnload event, after goApp.ReleaseForm(Thisform)

Then, When I Click on the X button, This is deactivated, The form keep on the screen and your window is activated.

I click on Show All And then on the search button.

Results:
_vfp.Objects[5].OTOOLBARAPP->tbrsistema
memory variable GOAPP->capplication
memory variable GOAPP.OTOOLBARAPP->tbrsistema
memory variable OUSER->usuario

I don't see any internal reference to an object of the form.

I need your help!
How is the next step to try to solve this problem??
Another Idea ???

Thanks very much in advance!
