I haven't seen this before. Can you open a new topic and attach the file to it? Did you try resetting the config?

You may have a look in one of the documents in my footer. I may later have time to fix your model. The idea is to use rather tangency and equality rather than coincidence.

You just have the settings in the wrong group: you're one level too deep, with your new setting in the MainWindow preferences area.
