Had a quick look, and what happens obviously is that ServerWindow::Window() can return NULL (and does, in this case, since the window which Magnify uses to call BScreen is an offscreen window). So I guess that, for offscreen windows, we'll have to resort to use the B_MAIN_SCREEN_ID (for compatibility), or return an error message, since Magnify is at fault here. The real problem, obviously, is that the app_server shouldn't crash :-)
