gEDA-user: Layer confusion?

[Dave McGuire <mcguire@xxxxxxxxxxxxx>]

  Hi folks, PCB question here.  I seem to recall Harry and Bob 
discussing this just a few days ago, but I think I've run into 
something different.  I've been working on the PCB layout for a side 
project off-and-on for the past two months or so, and I've just 
finished the layout...I went to create gerbers for it to send it to 
Advanced Circuits, and I always look them over in gerbview first.

  In PCB, all the pads and traces are on the layers they're supposed to 
be on...but in the gerber output, all the top traces are on the bottom 
of the board, and vice versa.  Traces, not component pads like (I 
think) Bob was seeing a week or two ago.

  Can anyone tell me what's going on here, and more importantly how to 
fix it?  Any advice would be greatly appreciated.

            Thanks,
            -Dave
