Thanks for the reply, Alizar77.
I think you're right about the entire town not meant to be seen on the screen at once. You need to use the trackpad to scroll around the town. But once I installed the update, my screen became smaller and I can't just scroll to the end of the frame to cause more of the town to appear. Now I have to click on the screen and then move the mouse to help it along.
I had that problem with a couple of their other games, too. Taking screen shots and sending to Township Support...I'll post if they let me know why this happened.
