Jerry, 

Please try the latest svn version which includes the fix for the ps
driver to include %%EOF at the end of the file. Hopefully this will
solve your Skim problems. Can you let me know if you see a blank page
when it refreshes? I see this with ghostview. I know why, I'm just
trying to ascertain if this is just a ghostview problem.
