If you have a 2nd screen attached, place Pulse in that 2nd screen then close it, it stores those co-ordinates (e.g. adhd_gui_x=2037 adhd_gui_y=150). If you then start Pulse later with a single screen, it launches Pulse off-screen. I have to manually edit the co-ordinates in order to make Pulse viewable).
