hidden connector lines

[jrwrk]

Hello,
I was createing a fairly simple drawing and lost connectors between boxes,
however they appear to be there I just can't access them. I say this because
when I go to put the connecters in again, I get the jump/bump on the new
connectors which indicate the original connector lines are there, they're
just not visiable/selectable.

any chance they are on a layer that is hidden?
