Changing the snapping threshold _should_ help. Don't forget that you're
working in "digitizer" inches - you'll need to multiply the threshold by
your scale to get equivalent ground distance.
If this still isn't helping, use the "snap to line" command in the Edit menu.
You can also specify a snapping threshold in v.support, though this is a
little risky. Save a backup copy before doing this, in case it snaps
lines that you didn't intend to!!
Best holiday wishes,
