I’ve been working on a project for days. Normally, when I select the line drawing tool in the Board Editor, a panel appears above my board where I can select the line width and the line drawing behavior. Yesterday, this panel stopped showing up. Also, pressing the Esc key at this point does not cancel the line I am drawing. Exiting LibrePCB and rebooting the computer does not fix the problem. Choosing a different project does not fix the problem.
Did I toggle some mode or is this a bug? I attached a screenshot showing that I selected the line drawing tool and the panel above the board is not visible.
