add-to-car--button.jpg
In Virtuemart when you set the action for product that is out of stock to "Displays 'Notify Me' instead of 'Add To Cart' button" it doesn't work both buttons show, actually the "Notify Me" button is just a link but supposed to be a button. I've attached a screen shot of what happens.
This has to do with the Virtuemart template customizations in Quark. When I switched to other default templates it works fine.
