That is interesting. Maybe it is related to the bug I found with debug
option and Peter C already has kind of solved?

Another idea: May it be related to the dirt traces which result of PCBs
internal rounding errors, resulting in very short traces, 0.01 mil or
so. I have generated a lot of then on my DSO board, but I always tried
to remove them again. These dirt may generate shorts?

Of course you can send a copy of your board to me, I can test with
pcb20091103. But I am not a developer and not too smart, so my chances
are not too good.

Best regards
