In Illustrator, when I apply Pathfinder tools (like Trim, Merge) it generates invisible paths (paths with no fill and no stroke). I believe this only occurs with compound paths.
These "ghost" paths often adversely affect later operations. I know how to find and delete them, but it is an annoyance to have to do so every time I apply a Pathfinder effect.
Is there a way to prevent this?
I suspect it may be something in my configuration because I cannot find evidence of other people having the same problem (or I was just calling it the wrong thing while looking for an answer).
