The purpose of the Busy Indicator is to provide global visual feedback that the application is currently busy.
When displayed on the Main Window, since any one of the Ready to Download Page, Ready to Install Page or Installed Page can be performing a task that is causing the busy state, and since the active page in the Product Status area can be switched while the application is busy, the Busy Indicator is located in an area that is visible regardless of which page is active.
If the application is not in a busy state, the Busy Indicator blends into the background. Once the application becomes busy the indicator appears in an indeterminate state.
