If Mark's coded a workaround, I hate to be the one to tell y'all but it doesn't work: I've got a P3/700 with an Intel chip that won't take any image larger than screen size without corrupting the image areas beyond the screen res -- and yes, that's the latest version of Blitz. Granted that machine is hardly hi-spec anymore, but if you're targeting low-end audiences, yes, be careful of this.
