Yes, there's a workaround, but it feels like one shouldn't have to
work around it. We Mac users are spoiled that way. :-)

I discovered last semester that (these) students find graphics VERY
appealing, so I wanted to introduce that on day 1. I'd rather have
them start off with
line([0, 0], [100, 100])
win = GraphWin()
myLine = Line(Point(0, 0), Point(100, 100))
