As the title says, double clicking removes the targeted trace node (both in PCB and schematic editor) also brings up the properties window. And this is quite an annoyance as this is not my intention. In previous version of the editor, this didn't happen.
I agree that this is a bug. A double-click event on a UI element should not trigger a double-click event on the underlying UI element. The fact that the double-clicked element is removed from the DOM doesn't change this.

This behaviour is quite a PITA. Double-clicking should not trigger two different actions.
