With kids running in and out all day... and the fact that you really have to hold the doors closed and practically turn the knob back to center before the old victorian mortise springs pop the latch out to catch it... I just end up with open doors all day.
Any hints on how to get these doors closing better? They are all well hung. And they do hit the latchplates, although sometimes the (tiny) door latch barely overlaps the strikeplate to keep it closed. But you just aren't able to push it firmly closed and think it'll take.
