   Yes, I had thought about that as well.  Fortunately (in my experience 
anyway) it seems to be rare.

   Usually yes; they get highlighted in orange, but sometimes the orange 
highlighting doesn't appear in sensible places.  If (as in my case) the 
power net is shorted to the ground net, and they're all over the board, 
PCB can't necessarily know where that short is, it seems.

   Yes.  I'll be watching that log window much more closely now.

   I like that method, but I was trying to avoid it because this board 
is very nearly done and I need to get a prototype built ASAP.  I was 
hoping for a "quick fix" suggestion, and several people have stepped up 
with some. (thanks!!)  I'm working on it again now with rested eyes.
