Used to have this issue on v1040s with a lot of screen elements. Clicking off of an item onto a blank space would take a while. Trick was to ctrl+click to deselect the item. Leaves you in the same state of having nothing selected, but without the wait.
+1 for this. Long time Visilogic user but transitioning one of our systems to the Unilogic series now and am sorely missing the larger rung comments as well. If not individually dynamic size, maybe a global option in settings?
