I noticed a new bug in Circle Dock.
I suggested that, when you click the mid-icon, the dock hides again. It works perfectly, and thanks for adding this to Circle Dock.
But, ok, you click on it. But, if you click while it hides, (makes the effect of 'opacity'), if you keep clicking on the mid icon, it stills showing up...
I guess, if you pressed once, it should hide (ok), but, you can't click on it anymore...
So, this is it.
