So I learned today that a child class's icon is created by merging the child's icon as displayed in the class properties with the parent's icon as it appears in the parent's properties (the child's icon being the top image in the merge and the parent's the bottom). This isn't obvious from normal operation since the default icons are the same size and thus the child's icon perfectly overlaps and thus displaces the parent's. However, I drew an icon that extends a little bit beyond the bottom of the border of where the default icon normally goes (in the parent icon). This change was propogated to my numerous child classes, and now the icon is cut off on like 100 vis and it looks dumb.
Technically, this doesn't change anything about my program. Since I never actually place the child vi's on a block diagram, I never see the icons except when editing the child vis or when they are calling each other (one child vi calls the other, which is rare). The code is only brought into the main vi via dynamic dispatch. That said, I'd love to know if there is a way to override the default behavior of how labview builds these vi icons. It's driving the pedant in me crazy.
