I answered a version of this question over e-mail but this phrasing is clearer. Some files and folders are virtual directories that don't have a physical path on your hard drive. Currently, Circle Dock does not support the drag and drop operations on these file types. You have to create a Windows shortcut for these directories and then drag and drop them onto Circle Dock. Circle Dock will execute the shortcuts.
For the second part about, I believe you want to disable movement of the dock and keep in on the bottom of all other windows except if it has focus. Someone on another messageboard has made this request and I'll be implementing it fully in Alpha 8 which will be out in about 1 week from today.
For now, you can disable Circle Dock from following your mouse around when you toggle the visibility by going to Settings -> Location and uncheck the follow the mouse option.
