Well, why should Windows save 2 Megabyte of screen memory for a simple editor if the few bytes of the text plus a few bytes of a routine that draws the text on screen can do just fine, too?
Anyway, it's not unproductive code. You just write your code in a way that it can not only draw your stuff once (i.e. the initial drawing) but every time this is needed.

OK, but it is preferrable that the programmer does not forget to call that code everytime it is needed. Isn't this wasted time during develpment I mean ?
