Re: vertical line disappear

You absolutely right. This appears problem of TexWorks. Depending on scale one or another vertical line appears or disappears, or I can see all vertical lines. I use TexWorks because this is only PDF browser which automatically refresh file after compilation. So I did not think about other option. Thank you

Sorry, I don't understand the problem ; see the attached picture. Maybe it's a problem from your PDF reader ?
