@felgallDec 03.2006 — #Decent browsers acknowledge the operating system supplied contextmenu as being attached to the right mouse button and therefore don't allow you to intercept contextmenu events at all. What you are asking for is therefore five times as impossible as something that can never happen at all. Less considerate browsers do allow web pages to intercept contextmenu events but even they allow the browser owner to disable the action that such an event triggers if they don't want it doing that. What you are asking for is therefore only achievable in some browsers and will only affect newbie web users using those browsers who haven't yet learned how to turn off such interference with their browser functionality.
