How do I minimize applications to Circle Dock?
  


The short answer is, "you can't": it's not technically possible.

Now here's the longer technical answer: When you minimize an application, it normally is represented on the Windows Taskbar as a "button". I say "normally" because there are exceptions to this, both Rocket Dock and Object Dock can host minimized applications. However, both of these programs are "docked" at one of the screen edges and that's a very important property and one that Circle Dock does not possess.

Windows requires that programs that intend to act as dock sites for minimized applications must themselves be positioned at a screen edge and not interfere with any other program that acts in a similar way - including the Windows Taskbar. Furthermore, the coordinates of the rectangle that will host the minimized act must be negotiated with Windows and any changes to that agreed before that change occurs.

So there are two barriers to Circle Dock acting as a host for minimized application's icon:
·     Circle Dock floats freely and can be positioned anywhere you choose and it can be rotated
·     Circle Dock is not bound to a screen edge.
