I'm in the part of the game where Nancy is supposed to scare away the squirrel by mounting a pie pan on a string attached to the pole and have it next to the windmill in the park. There's no hot spot to the left of the windmill like it shows in the walkthrough. I'm stuck.

Check out this thread here.

You may have a different problem, but it's also worth noting in that thread that the squirrel/windmill sequence in the game did not work for this player until the mouth sculpture puzzle in the park had been completed.

Yup. That was the problem. Thanks. Problem solved.

I am glad that it helped.
