Modeless Form Close Button Crashes

Hi,

I’m doing quite a bit of wheel spinning trying to close a modeless form with a close button instead of the user clicking the “X”. I’ve pasted in some sample code below. I’ve tried a self.Close(), which crashes Rhino and tried what is in the pasted code below with no success. Can someone tell me what I am doing wrong?

I posted something similar back in May and never got an answer: ETO Modeless Form Close Button

Test():
        print ("Hi")
       
    # Form Closed event handler
    def OnFormClosed(self, sender, e):
        print("the form has closed")
        # Dispose of the form and remove it from the sticky dictionary
        if sc.sticky.has_key('sample_modeless_form'):
            form = sc.sticky['sample_modeless_form']
            if form:
                form.Dispose()
                form = None
            sc.sticky.Remove('sample_modeless_form')

    # Close button click handler
    def OnCloseButtonClick(self, sender, e):
        print("the form has closed")
        # Dispose of the form and remove it from the sticky dictionary
        if sc.sticky.has_key('sample_modeless_form'):
            form = sc.sticky['sample_modeless_form']
            if form:
                form.Close()
                form.Dispose()
                form = None
            sc.sticky.Remove('sample_modeless_form')


    # OK button click handler
    def OnOKButtonClick(self, sender, e):
        print("clicked")



    ## End of Dialog Class ##


def Test():
    
    # See if the form is already visible
    if sc.sticky.has_key('sample_modeless_form'):
        return

    # Create and show form
    form = ETOModelessForm()
    form.Owner = Rhino.UI.RhinoEtoApp.MainWindow
    form.Show()
    
    # Add the form to the sticky dictionary so it
    # survives when the main function ends.
    sc.sticky['sample_modeless_form'] = form
