Interesting Dock Note

Recently I’ve noticed an odd Dock issue. For us to add to our dock’s we just need to simply drag the icon to our dock. But twice now I’ve noticed installers needing to restart the dock to add items to it. The first time I just figured it was a bug in the HP driver installer I needed. But after the recent iTunes update I realized that it is likely an odd bug of some sort. I only noticed this because my desktops change.
