Homebrew PCBs

Thanks a lot Robert.  So thhhhaaaats what that Net class menu is 
for!  
  I don't mean to flood the group with questions specific to a layout 
program, but everyone here is so good.  I hope more people can 
bebefit from these.  Maybe I'll make a little mini-tutorial as an 
alternative for newbies like myself who find software manuals to be 
kryptonite once I get everything figured out.
  
  I've got another one.  I just dug a hole I can't figure out how to 
get out of...I noticed something in my circuit I wanted to change, 
yet I was already routing, so I stopped the autorouter in mid-route.  
I then removed a component from my schematic.  After that, I noticed 
the router was still half-done, so I went back to the board and told 
it to "End Job".  When I did, it somehow magically replaced the 
component I had just removed, restoring the board to the way it was 
when routing had started, but here's the bad thing...the component 
was still missing from the schematic.  I then promptly got the error 
message that the schematic and boards didn't match, that no 
forward/backward annotation would be allowed, and that my first born 
children would be found and executed.  Okay not really...just the 
first parts.
  I noticed though that the part it replaced wasn't wired up (when I 
say "wired up", I mean it didn't have the straight little yellow 
unrouted lines between it and the other components it should be 
connected to).  When I went to the schematic and replaced the part, 
then went back to the board, it still wasn't wired.  So, I deleted 
the component from the board and the schematic.  I then replaced the 
component with a brand new one on the schematic, BUT, and here's the 
bug butt, it nor any others will show up on the board now.  (It was 
serious about the forward/backward annotation thing).  How do you 
restore that function once you've gotten it out of sync?

Thanks a million again
