I'm not sure what you mean by using hide and show on menu forms. Using hide/show on a form is not creating multiple instances of that form. Rather it is making it invisible. When a form is hidden, it is still taking up memory, but regardless of how many times you hide/show it the memory footprint will remain the same.
