gEDA-user: Next problem, PCB looses rats

[Mike Bushroe <mbushroe@xxxxxxxxx>]

   OK, I have the layout. I found that some symbols don't have explicit OR
   implicit power connections. Others use VDD and VSS instead of Vcc and
   GND. I found where I have moved a component slightly a caused a short
   between ground an power. I got all that fixed. But every time I start
   to run the power buss, I reach a point where pins are highlighted
   green, but the rat lines disappear, and the DRC makes it impossible to
   run a trace to the pin. I have to keep saving the layout, exiting the
   program, and starting over. Even reloading the net list and displaying
   the rat lines does not help. This is slowing things down quit a bit.
   But I don't think I can build a 4 layer board at home, and with only
   two layers, there is no ground an power planes, so I want the power and
   ground lines thick and well laid out, so I don't want to rey
   autorouting just yet. What I am doing wrong this time?
   Mike
