Hi, We can reproduce this problem, can you try to place hot `W` to draw a wire and ` L` to draw a line?

Hello -- I am using a mac with a single button mouse. If I am trying to draw a single line, I cannot. I draw the line, and then I have no way to exit drawing the line without it disappearing. Please advise. I would just like to draw a straight line in the schematics library view.

@xiphocoleon I figured this out. I had to set my one-click Mac Magic Mouse to do "right clicks" by clicking on the right-hand side of the mouse. I was able to make this right click setting in my computer's System Preferences. However, it would be nice to be able to draw lines without a right click.

@xiphocoleon Thank you! I had the same issue. I could not figure how to exit drawing without the line vanishing. I'm glad I did a gsearch and found your answer.
