I think I know what you mean, but it's just a key away from removing that "blank" screen (which is called a frame IIRC). For me, (ctrl-t backspace) remove the current frame. I like the flexibility of Stumpwm where it differentiates between the space taken by an application and where it fits on the screen (Frame) vs the application. The scenario you are describing happens if you have 2 frames while only one app running. Otherwise the next app would just fill that frame that is now available. Personally it doesn't bother me.. I'll just either remove the frame with (ctrl-t-backspace) and then my only app will now be full-screen on that first frame. Or I'll open another app in that empty frame, such as a terminal.
