Hi Isaac,

Checked on the test file and it was indeed giving problems, I've made
some changes in svn which I think resolve them...
- in wireframe draw mode, dont snap to faces, ignore depth and snap to
verts/edges only.
- reduce radius for picking rulers (in your example it was too easy to
drag points by accident).
- draw snap circle so you can tell when snapping occurs (makes it more
obvious theres no face snap in wireframe view).

In your example there are still cases where you may not want to snap
to other unselected objects, but in those cases Id suggest using
localview or hiding the objects.
