This is the way it's supposed to work. You have two event handlers, both are executed. I would suggest the following:

In the parent form, add a method

Protected Overridable Sub OnOKButtonClick()
    MsgBox("Parent Form OK Button Clicked")
End Sub

which you call from the button's click event. In the inherited form, remove the button click event handler, and override the OnButtonClick method

Protected Overrides Sub OnOKButtonClick()
    MsgBox("Inherited Form OK Button Clicked")
End Sub

This should accomplish what you are after.
