Easy to test. Make a box. Add a couple of persistent construction lines that align with edges. Try to select the edges - only the ones without construction lines can be selected. Looks like it selects the construction line instead of the edge.
Could it be made so that the edge gets preference in this situation instead of the construction line? But don't really want to lose the ability to select the construction line altogether, though.
Hi Tony, thanks for reporting this. For the next beta I've adjusted things so that edges will be above construction lines for hit testing purposes so this case should behave better in the next beta.
