I am editing a project in easyeda. A red track is displayed. I move the mouse over the track, but do not click. The track turns grey, but the green circles nodes are not displayed. I double left click. A green circle node is inserted, and the other green circle nodes are now displayed. A red track is displayed. I move the mouse over the track, and left click. The track turns grey, and the green circle nodes are displayed. I double left click. Nothing happens. A green circle node is NOT inserted. So I find that double left click to insert a node always works if the green circle nodes are NOT displayed, and never works if the green circle nodes ARE displayed.

@kenneth_howlett Hi， please click the track segment again to double click to add the node, because the first click the mouse will select the whole track segments, only for one segment can double click to add node
