Since you have a one-to-one relationship between your forms and toolbars, you could explicitly hook them together with bidirectional object refs. Your form already has one to the toolbar, so just add one from the toolbar back to the form:

this.oToolbar = createobject( ..., thisform )

*toolbar.Init( roForm )
this.oForm = roForm

now your toolbar can make callbacks to form methods. One button's click might be:

this.parent.SaveForm()

* toolbar.SaveForm
this.oForm.SaveForm()

* toolbar.Clear
this.oForm = .null. && clear the form pointer

You have to make sure you clear these object references during the form.Destroy:

this.oToolbar.Clear()

But in general this might get you around your _screen.ActiveForm.ActiveControl issues. Because your SaveForm method can generically make sure that the last control has committed its changes to its ControSource.
