Sorry about this but here we have another simple little crash Easy-PC any time you want to feature. In a schematic design or component add a "single line shape" Before adding it right click and select "Free Movement" and bang you are dead , simple as that. It works ok for a triangle shape.
I've confirmed that one as well. It only works if you use the menus though. The icons are OK. It's also been fixed, so any user requiring a patch, please email <support@numberone.com>.
It will also be incorporated in release 12.0.6, of course.
