I have Nexus undocked and tend to move the icon around if it gets in the way. If I move it too close to the edge of the screen, it automatically docks to the edge and I have to go to the settings to undock it. This is extremely irritating when I move the icon from one screen to another (I run four screens) because it will dock to an edge when cross between screens. After docking, it won't accept Alt-mouse to move it until I undock it.

Is there any way to keep the Nexus icon undocked even when close to or crossing a screen edge?

Dock Properties (or Nexus Preferences when running the free version of Nexus, which is not your case) -> Behavior tab -> More Options button -> clear 'Enable Snap-to screen edges'.

That setting is global so disabling snap-to there will disable that behavior for all docks, shelves, etc

Thank you! I had no idea that box existed. Usually I know my way around the preferences but that one escaped me.

Winstep applications still pleasantly surprising you even after all this time lol

Well, hell, they've got to be, seeing as they include everything including the kitchen sink... LOL!
