Hello, I have met that situation before, I later figured out maybe there are some tips you should follow if you want to chang the location of your icons. When you drage icon 1 to change its location to where icon 2 locates, you need to make sure that icon 1 and icon 2 are excatly overlapped while draging, then icon 1 will locate where icon 2 initially locates.

If you try to drag icon 1 to the location between icon 2 and icon 3, sometimes it might be unsuccessful. Hope you will find this helpful.

I placed a shortcut to the Circle Dock.exe file in my Windows startup folder, and when the Circle Dock runs as the Windows starts, it seems that the background and the other icons are seperated. But if I start it again, then everything will be all right.

Thank you very much for this great dock! And I have a small question: How could I autorun the dock when windows starts? I did not find the right way
in the setting options.

Still, a great thank to your work! ;D
