Creating unintended wire segments

I think fritzing is a really cool program. I like the feature where you can click a part of the breadboard and all parts of the circuit that are connected to that point light up in yellow. The problem is, if I move my mouse ever so slightly when I do that, it creates a wire segment which starts and ends on that point. And depending on colors, it can be impossible to see, so you might not even know you just did that.

Is there any way to avoid doing that? It would be nice if it would only create a new wire if you move the mouse a certain amount.
