This sounds like the same, (or at least similar to,) problem I’m having in Linux: Piece tracing trouble
@Karu Am I correct in thinking that this is just if you want to change something when you first get the workpiece tool dialog? Does it get by if you use the dialog in the piece mode? If it is the issue which @Douglas mentioned, some people have found that using the arrow (& Return) keys to navigate the menu works.
