I'm on 10.8.3 and I see the grey screen w/ no plot.
Skip's still on that "Blue" Quartz UI setting, the stop light colors on the window buttons give it away, so he may not have done a full rebuild of p9p in a while. I can't get all of p9p to compile on 10.8, that mean's there are likely a few bits missing that never made it forward from my pre 10.7 builds.
I've tried forcing a flush image in during the event loop and after resizing the window. All that does is give a clean white background that didn't use to exist. Still no real plot info.
To get around the drawing problems I always went w/ grap | pic | troff | tr2post | psfonts > t.ps.
