I've been using PSFIG very happily for some time now. I recently hunted 
around on whitechapel... for a new version, and loaded 1.8 onto my machine. 
I quickly unloaded it as it didn't do what I wanted. The same applies for 
version 1.9 which I just tried.

Here is a line from my LaTeX file:

\centerline{\psfig{figure=frontier.eps,height=4in}}

Versions 1.7 and earlier hunt, as desired, for file frontier.eps in the 
current directory. Versions 1.8 and 1.9 instead talk about frontier.eps.Z, 
which exists nowhere on my disk.

What am I doing wrong here?

Thanks for any help
