If you're in an application that gives you a link that you can click on, the spinning circle usually means that Windows is busy; it's doing something... it might very well be loading IE9. It's not until IE9 has finished loading that it becomes visible and takes over the screen.
Circle Graph: A graph that displays categorical data in the form of a circle. The circular region is divided into a number of pie-shaped sectors to represent portions of the data. This type of graph is sometimes refered to as a pie chart. A circle graph shows how parts relate to a whole and to each other. The area of each sector indicates the percentage of the whole that the part represents. Example circle graph: In this example, Clinton had almost 50% of the popular vote, so the red sector fills in half of the circle. Dole got a smaller percentage of the popular vote than did Clinton, but he got more than Perot did.
