Hi Jacob- The IDV doesn't support dual monitors very well. You need to keep the Dashboard on the initial monitor that it was started on. You should be able to move the display to a new monitor once it's created. For the error below, what were you doing when this occurred? Were you making a new display or trying to save an image?
