Oh I can calculate SWR, etc. I remember my Maxwell's equations and all but
there's little chance that I could actually see the traces anymore... ;-)

I'm running 4.2.2 (28). Pull the latest download from the ADC web page and
re-install it. I suspect that you've got an out-of-sync install of it and/or
the Xcode tools and/or the Mac OS SDK's.
I use SHARK 2-3 times a day. Maybe I'm just keeping it warm. ;-)
