I started working with PCStitch 9 and created a couple of fonts. In each case, when I used the font in a pattern, random horizontal lines appeared; a few times there would be vertical lines also. I was able to find a few mistakes in the font files and removed the lines I could find, but random lines continued to appear.
I hoped the issue wouldn't affect PCStitch 10, but unfortunately it continues. When (re)creating the fonts I was especially careful not to make mistakes during the process, should there be lines I thought I had deleted but actually hadn't, but so far horizontal lines continue to appear in the pattern while I can't find any random lines in the font file.
