I'm sorry. I don't see the little red icon. As far as I can tell,  
nothing has changed in the window at all except the Code Pad now has  
a line that says "new Circle();" in it.

Oooohhh. I just figured it out! If I type in the statement WITHOUT  
the semicolon, I get the icon that I can drag onto the bench. WITH  
the semicolon, no icon.

That will be very confusing to the students.

I tried out that technique using the Shapes project, but couldn't  
make it work. I'll have to play with it some more.

But, since unit testing isn't introduced until chapter 6, is there  
something that can be used from day one that will allow them to  
record their actions so they can replay them over and over, much like  
a macro in Excel?
