well whats happening, is on google sketch-up, when i use it on my home computer, normally when u mouse over a face, blue dots will appear on that face to show you what face you've highlighted. I'm not talking about when you select like a line, and it turns blue, but the blue dots. They appear when I'm using a school computer and i downloaded sketch-up twice on my home computer and they still wont show up, what should i do to get them to appear?
