Ahh, could it be that the layer you are attempting to trace is in a different projection than that you are tracing in?

It doesn’t matter how many nodes I add. It does the same thing when I autotrace. Autotrace should come up with the same line, but it doesn’t. I don’t understand what the problem is. I assume it is some setting or other that I need to change, but what?

Never the less, the results you are getting are by design, even a "smooth continus curving line" or a "wiggly line" (i like that one:) is made up of many straight line segments as you describe. You have two options. When digitizing, add lots more nodes closer together to make the line appear smoother (when printed or even viewed at a normal zoom level they will apear smooth). But adding more nodes may not be feasable due to time limits. Secondly, if you double click the ployline you wish to smooth, check mark the "smooth" check box, this will give more visual effect of smoothing. But the smoothness is still be related to the density of your nodes and their spacing.

I am trying to create a polyline following say a river. As I move along the river, the line I am creating is not smooth. It appears as a series of jagged straight line segments, not a smooth continuous curving line or a wiggly line such as a stream. What do I need to change to be able to draw a “wiggly” line? Thanks.
